Answer 1

Answer: A. $17.28

Explanation:

Given : Lindy works at a pizza restaurant and gets a 10% employee discount.

here m, 10% can be written as 0.10.

She knows that if she orders d drinks and a medium pizza with t toppings, her total cost can be found using this expression:
`0.90(2.25d + 1.40t + 6)`

For d= 4 and t= 3 , we have

`0.90(2.25(4)+ 1.40(3) + 6)\\\\=0.90(9+4.2+6)\\\\=0.90(19.2)=17.28`

Therefore, the total cost for Lindy = $ 17.28

Answer 2

Option A. $17.28

Explanation:

we have the expression for the cost

`0.90(2.25d+1.40t+6)`

In this problem we have

`d=4, t=3`

substitute the given values in the expression to obtain the cost

`0.90(2.25(4)+1.40(3)+6)=\$17.28`
