Tony is a salesperson who earns $560 per week plus $60 for each sale he makes. This week, he wants to earn at least $920. Write and solve an inequality that represents the number of sales Tony must make this week to earn at least $920. Write a sentence to represent the solution set in the context of the problem.

920 = 560 + 60(x)  He must make at least 6 sales to have earned $920

Step-by-step explanation:

Step-by-step explanation:

1) To solve this question easily, cross multiply first. Multiply the denominator of the first fraction by the numerator of the second fraction, and multiply the denominator of the second fraction by the numerator of the first fraction:

2) Now, solve like you would and isolate y. Subtract both sides by 10y.

3) Then, subtract both sides by 7.

4) Finally, divide both sides by -7 to receive the answer.
