Question

Sheila's job has a base monthly salary of $1,300. For every sale she makes, she earns $50. If Sheila's goal is to earn $5,450 this month, how many sales does she need to make?

Answer 1

If we let x be the number of sales that Sheila makes this month, then she would make $50 for each sale (or 50x ) plus her base salary of $1300, which gives us the following expression: 50x + 1300.

Since Sheila wants to make $5450 this month, we can set up the following equation and solve it:

50x + 1300 = 5450

50x = 4150

x = 83.

Thus, Sheila must make 83 sales this month to earn $5450.
