Question

Marco borrowed $150 from his brother he has paid back 30% so far how much money does Marcus still owe his brother

Answer 1

Hello~

The question says that Marco borrowed 150$ and paid back 30%.
30% of 150 is 45, so it seems that Marco has paid $45 back.

Marco needs to pay 70% back to his brother to get out of his debt.
In other words, $105 back.

Hope that helps!

Answer 2

Marco owes $105 to his brother

Step-by-step explanation:
The first step in solving this is to find 30% of $150 to see how much Marco had already paid his brother. Since 30% = 0.30, we can do 150 x 0.30 (the word "of" in math USUALLY means to multiply.) That gives us 45, so now we know that Marco has already paid back $45. Since we want to know how much money he still has to pay, we subtract how much he already paid back (45) by the total amount (150.) 150 - 45 = 105, therefore Marco owes $105.
