Maria earned 126 in simple interest from her savings account. if she invested 450 for 7 years, what was the inrest rate?

Step-by-step explanation: 450 * 7 * i = 126

3150 i = 126

i = 126/3150

i = 0.04

0.04 = 4%

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
