Nina saves 40% of her summer job earnings for college. this summer, she earned $200 more than last summer, and she saved $900. write and solve an equation to find her earnings last summer.

(900 ÷ 4) x 10 -200 = 2050 And this will equal last Summer's earnings

Step-by-step explanation:

So we know that 900$ is equal to 40% and that we can simplify this

900 ÷  4 = 225

40% ÷  4 = 10%

Therefore:

225 = 10% and

2250 = 100% of earnings
