Select the correct answer.
Lindy works at a pizza restaurant and gets a 10% employee discount. 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).
What is the total cost for Lindy and her friends to order 4 drinks and a medium pizza with 3 toppings?
A.
$16.52
B.
$17.28
C.
$15.69
D.
$28.40
To find the total cost for Lindy and her friends, we can substitute d = 4 and t = 3 into the expression 0.90(2.25d + 1.40t + 6):
0.90(2.25(4) + 1.40(3) + 6) = 0.90(9 + 4.20 + 6) = 0.90(19.20) = $17.28
Therefore, the correct answer is B. $17.28.
