Answer:
$195
Explanation:
To solve a percent problem, you can use the equation: part %
------- = -----
whole 100
You want to find 30 percent, so the % would be 30. You also want to find 30% of 150, so the whole would be 150 and the part would be x. Cross multiply to get 100x = 4500. Then, divide 4,500 by 100. The equation should look like this: x = 45. Add 45 to $150 to get $195. So Aaron has $195 at the end of the week.
