Answer:he must make $812.5 or more in his paycheck
Step-by-step explanation:
Let x represent the amount if money that Ethan must make on his next paycheck.
Ethan needs to save at least $500 to purchase a new dirt bike. So far, he had saved $175. If he hopes to use two-fifths of his next paycheck to cover the amount, then the equation becomes
175 + 2x/5 ≥ 500
2x/5 ≥ 500 - 175
2x/5 ≥ 325
2x ≥ 325 × 5
2x ≥ 1625
x ≥ 1625/2
x ≥ 812.5
