Angelo earns $2,080 each month. His total deductions are 30% of his pay. How much is deducted from his pay each month? 

       A. $693.33   B. $69.33   C. $62.40   D. $624.00

Respuesta :

C. $693.33. Just round. It helps. Round 2,080 to 2,100. Then whats 30% of 2,100? It's easy just think of 21 divided by 3, which equals 7. So, 700 and the closest answers to that is $693.33. That's just the easy way instead of doing the math out. And it is also common sense that B or D wouldn't be it. So your left with C or A. :)
To how much is deducted from his pay each month, you just need to multiply the rate of his deductions by the amount he earns
2,080×0.3=624

So the answer is D

Hope it helps!
