Hello There!
We know that Maria earned $450 in a total of 5 days so we need to find out how much money she earns in just 1 day.
To find this, we just divide 450 “the amount of money Maria earns in 5 days” by 5 “number of days it takes for Maria to earn $450”
“450 ÷ 5 ≈ 90”
Maria earns around $90 in just 1 day.
