Felipe is planning a party. He has $50.00 to spend on sandwiches that cost $2.50 per person, $25.00 to spend on drinks that cost $1.50 per person, and $25.00 to spend on gift bags that cost $3.00 per person. Which expression could be used to show the amount of money he will have left over if x people attend the party? 50 + 7 x 100 minus 7 x 2.50 x + 1.50 x + 3.00 x 100 minus (2.50 x minus 1.50 x minus 3.00 x)

Step-by-step explanation:

given data

amount for sandwiches=$50

amount for drinks is $25

amount for gift bags=$25

total amount=$100

the number of persons be x

cost of sandwiches= 2.5x

cost of drinks= 1.5x

cost of bags =3x

therefore the total cost is

2.5+1.5+3=$7

the balance is

total amount -total cost

Balance=100-7x

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0
