Susan ordered x pizzas for $11 each. In addition, each pizza topping cost $4 for the first pizza and $3 for each additional pizza. If each pizza had exactly one topping, which of the following gives the total cost, in terms of x, of the pizzas Susan ordered.

a) 11x + 1
b) 11x + 4
c) 14x + 1
d) 14x + 2
e) 14x + 4

Please assist with above problem.

Hi alanforde800Maximus,

What is the source of this question? I ask because the prompt does not explicitly state whether the pizzas actually have the SAME one topping or not. GMAT questions are carefully worded to eliminate this type of confusion, so you might be studying from a questionable source. I'm going to assume that the pizzas have the same topping...

This question can be solved by TESTing VALUES.

IF... X = 2, AND the pizzas have the SAME topping, then Susan would have spent a total of ($11)(2) + $4 + $3 = $29

Final Answer: C

total X pizzas for 11 each = 11x
topping cost 4 for first and 3 for rest(x-1)
4 + 3(x-1) = 3x+1
Total costs = 11x+3x + 1
=14x+1

SO C

?

Seems like you're manufacturing ambiguity to me. The first one-topping pizza you order is $15, and each additional one-topping pizza is $14. No mention is made that the same topping must be ordered on each pizza, and the question is unanswerable in Problem Solving under that assumption with no further data.
