The watch Bea would like to buy costs $10 less than 2 times the amount she has saved. The watch costs $50.
How much money does Bea have saved?
Choose the steps that show how to solve this problem using arithmetic.
O A.
1. Start with the cost of the watch: 50.
2. Subtract 10: 50 - 10 = 40.
3. Multiply by 2: 40.2 = 80
So, Bea has $80 saved.
OB.
1. Start with the cost of the
watch: 50
2. Add 10: 50 + 10 = 60
3. Divide by 2: 60 - 2 = 30.
So, Bea has $30 saved.
C.
1. Start with the cost of the watch: 50.
D.
1.start with the cost of the watch:50
2.subtract 10:50 -10 = 40
3.divide by 2: 40 divided by 2 =20
so bar has $20 saved.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
