Answer:
He earns $540
70% of his money went to savings
Step-by-step explanation:
9 weeks x 5 days a week = 45 days

Answer:
of what shape
Step-by-step explanation:
Answer:
22 projects did not receive a perfect score
Step-by-step explanation:
12% or 25 is 3, meaning 3 got perfect scores. You would subtract 3 from 25 to get the amount of projects that didnt get a perfect score.
50% decrease then 100% increase: same as the original; the number is halved then that new number is doubled, which brings it back to the original, x * 2 * ¹/₂ = x (¹/₂ and 2 cancel out)
50% increase then 33¹/₃% decrease: same as the original; x * ³/₂ * ²/₃ = x (³/₂ and ²/₃ cancel out)
20% increase then 25% decrease: less than the original ; x * ⁶/₅ * ³/₄ = ⁹/₁₀x
$10 increase then $10 decrease: same as the original; x + 10 - 10 = x
25% increase then 20% decrease: same as the original; x * ⁵/₄ * ⁴/₅ = x
