Question

Every week, Petra saves 1/4 of the money she earns at work. Last week, she earned $60 working. This week, she saved $10 more than she saved last week. How much did Petra earn working this week?

Answer 1

$100

Explanation:

she earned $60 last week, to get how much she earned you'll take 60 and multiply it by .25(1/4 in decimal form) which would mean she saved $15 last week, so she needs to save $25 this week and I tested until I got to $25. equation is .25x$100=$25
