Answer: After 20 laps Paula will have more money than Jackie.
Step-by-step explanation:
Let x = Number of laps.
Given, Paula has $10 and earns $0.50 per lap she runs for her school’s fundraiser.
i.e. Total amount Paula has =$ [ 10 +0.50 (Number of laps)]
= $ [10+0.50x]
Jackie has $15 and earns $0.25 per lap she runs for her school’s fundraiser.
i.e. Total amount Jackie has =$ [ 15 +0.25 (Number of laps)]
= $ [15+0.25x]
When Paula has more money , then
