Olivia and Evelyn are each saving money. Olivia starts with $200 in her savings account and adds $10 per week. Evelyn starts with $50 in her savings account and adds $25 each week.
a. After four weeks, who has more money in their savings account? Explain how you know.
b. After how many weeks will Olivia and Evelyn have the same amount of money in their savings accounts?
Here's the answer I got:
A. After 4 weeks, Olivia has $240 and Evelyn has $150. Olivia has more money in their savings. Olivia started with $200, after 4 weeks Olivia had saved 40 dollars because she adds 10 each week. Evelyn starts with $50 and adds 25 dollars each week, 25x4 is 100 so in total she has $150.
B. After 10 weeks they will both have $300 in their savings.
