For this one, we need to make an equation to make it look easier (0.10 × m) + 500 = 1280 We solve for m Subtract 500 from both sides and we get 0.10 × m = 780 Now, divide both sides by 0.10 And m would be equal to 7800 Let's see if this is correct. Five hundred dollars more than 10% of m We found that 10% of m is 780, now we add 500 to make the statement true. It will give us a total of 1280, which is equal of what the question says. I hope this helps. YOU'RE WELCOME :D
