For senior class pictures, a photographer charges x dollars to make a negative,
dollars for each of the first 20 prints, and
dollars for each print in excess of 20 prints. If $80 is the total charge to make a negative and 30 prints, what is the value of x?
选项
A、3
B、4
C、5
D、6
E、7
答案
C
解析
The correct answer is C. You are given that the cost of the negative is x dollars and that the cost of the first 20 prints is
dollars per print. You are also given that any number of prints over 20 is
dollars per print. The question stem indicates that $80 is the total charge to make a negative and 30 prints. You know that the first 20 prints will cost
dollars per print and the remaining 10 prints will cost
dollars per print. Set up an equation and solve for x, as follows:
x + 14x + x = 80
16x = 80
x = 5
