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.
(i) X pizzas costing $11 each: 11x
(ii) X toppings costing $4 for the first one, and $3 for each subsequent pizzas: $4 + $3(x-1)
Therefore total cost = (i) + (ii) = 11x + 4 + 3(x-1)
Simplifying: 14x + 1. The answer is C.
