If your choices are

A. C = 2.99x - 50
B. C = 50 - 2.99x
C. C = 50x - 2.99
D. C = 2.99 - 50x

2.99x

That’s the money you owe for the cherries. That eliminates choices C and D.

50 - 2.99x

When x is zero you should get 50 dollars back, so that eliminates A. You get 50 dollars back minus the money that you owe for the cherries, so that's choice B.

B. C = 50 - 2.99x
