Respuesta :
Oliver's living expenses- 520(.1)=$52
This week Oliver will get paid $572 and he will take 10% of that for living expenses which would be $57.2 making his total spending money $514.8
You can calculate the 10% of the usual amount and then add it to usual amount to get this week's salary and then can subtract the new amount's 10% to get the expense.
Oliver is left with $514.8
How to get percent of some amount?
You just multiply that amount with the value of percent and divide by 100.
Thus, if you want to calculate 20% of 200, then it is calculated by:
[tex]200 \times \dfrac{20}{100} = 40[/tex]
How to calculate the amount Oliver is left with?
His usual salary = $520 per week
He earned this week = Usual salary + 10% of usual salary
10% of usual salary = [tex]\$520 \times \dfrac{10}{100} = \$52[/tex]
Thus, earning this week = $520 + $52 = $572
Amount spent = 10% of this week = [tex]572 \times \dfrac{10}{100} = \$57.2[/tex]
Thus, left amount is calculated by:
Left amount = Salary this week- amount spent
Left amount = $572 - $57.2 = $514.8
Thus, Oliver is left with $514.8
