Step-by-step explanation:
1.
¢78 per pack of 6 labels
costumer wants to buy 34 labels
= 34 labels x ¢ 78
6 labels
= $4.42
2.
bedroom = 14 ft. x 16 ft.
carpet cost = $2.49 per ft²
padding cost = $1.81 per ft²
find: total cost of carpet and padding
solution:
bedroom area = 14x16 = 224 ft²
carpet cost = $2.49 per ft² x 224 ft² = $557.46
padding cost = $1.81 per ft² x 224 ft² = $405.44
total = $ 963.2
3.
three makes = $9.87 per hour
two makes = $15.35 per hour
one makes = $17.98 per hour
one makes = $23.47 per hour
find: average pay for the seven workers:
solution:
add all rates divide it by number of workers
= 9.87 + 15.35 + 17.98 + 23.47
7
= 66.67
7
= $9.52
4.
gasoline truck = 10,000 gallons full
if 4,781 gallons are delivered to gas stations
each gallon weights = 7.5 pounds apx.
find: what is the weight remaining gallons of gasoline in the 10,000 gallon tank?
solution:
a truck delivered 4,781 gallons to a 1 station
10,000 - 4,781 = 5,219 gallons
therefore, the weight of the remaining gasoline in the tank is:
= 5219 gallons x 7.5 pounds
gallon
= 39,142.5 pounds
alternatively,
if a truck delivered 4,781 gallons per station:
10,000 = 2.09 (this means a gasoline truck can only deliver
4,781 two gas stations )
the remaining gasoline in the tank is:
= 10,000 - (2 x 4,781)
= 438 gallons of gasoline
therefore, the weight of the remaining gasoline in the tank is:
= 438 gallons x 7.5 pounds
gallon
= 3,285 pounds
5.
checking account balance = $1,266.73
write checks for $456.99, $35.00, $576.91 and $567.91
made a deposit of $892.14
find: what is your new balance?
solution:
= you write checks which is:
= $456.99, $35.00, $576.91 and $567.91
= $1,636.88 (note this is not a withdrawal)
this means it doesn't affect the balance
= deposit of $892.14
new balance = $1,266.73 + $892.14
= $2,158.87
alternatively,
if the write checks has been withdrawn, then deposited $892.14
the new balance would be = $1,266.73 - $1,636.88 + $892.14
= $521.99
1.
approximately 1250 people will be coming to get flu shot
if the shots are packed by the dozen:
find: how many dozen should be ordered to cover the estimate?
solution:
= 1250 people x 1 dozen
12 flu shots
= 104.17 ⇒ 105 dozens
therefore, 105 dozens is required to cover 1250 people
2.
wall is 81 ft wide x 52 ft tall.
paint will cover 500 ft² per gallon.
if paint cost $14.99/gallon
find: how much will it cost for enough to paint to cover the wall?
solution:
wall area = 81 x 52
= 4,212 ft²
paint required = 4,212 ft² x 1 gallon
500 ft²
= 8.424 gallons of paint needed.
therefore, the cost of paint to cover the wall is:
= 8.424 gallons x $14.99/gallon
= $ 126.27
3.
40 hours past. overtime pays = 1.5 times the rate
50 hours past. overtime pays = 2 times the rate
rate at less than 40 hours = $16.82
worked 56 hours in one week.
find: how much you earned?
solution:
normal = 40 hours x $16.82 = $ 672.8
over 40 = 10 hours x 1.5 x $16.82 = $ 252.3
over 50 = 2 hours x 2 x $16.82 = $ 67.2
total = $ 992.38
therefore, the total money earned is
$ 992.38
4.
20 ft long piece of steel weights 2.2 ton
4 ft is cut off
find: weight of the 4 foot in pounds
solution:
weight per foot = 2.2 ton
20 ft
= 0.110 ton/ft.
weight of four ft = 4 ft. x 0.110 ton
1 ft.
= 0.440 ton x 2,240 pounds
1 ton
= 985.6 pounds
5.
odometer reads 52,513 miles
returned from trip = 84,756 miles
average gas mileage = 23.8 mpg.
find: how many gallons did you use?
solution:
mileage = 84,756 - 52,513
= 32,243 miles
gallons used = 32,243 miles
23.8 mpg
= 1,354.7 gallons
