We have a question: Felix is chopping down trees in his backyard. For every 13 trees he chops down he needs to get his axe resharpened. It cost him $5 to sharpen his axe. If he spends $35 on axe sharpening, at least how many trees has he chopped down?
And an answer: 91
So how you got the answer?
He has sharpened in 7 times because 35 / 5 = 7. He has chopped down 91 trees because 7 x 13 = 91.

We have a question: On Tuesday, Liza had $800 in her checking account. On Wednesday, she paid her rent, $450. On Thursday, she deposited her $1500 paycheck. On Friday, she paid her electricity and internet bills which were $117 and $100, respectively. Then on Saturday, she paid her phone bill, $70. How much money is left in Liza's account?
And an answer: 1563
So how you got the answer?
On Wednesday, Liza had $800 - $450 = $350 left in her account. After depositing on Thursday, she had $350 + $1500 = $1850 in her account. On Friday, she paid a total of $117 + $100 = $217 for her electricity and internet bills. So, $1850 - $217 = $1633 was left on her account on Friday. After paying her phone bill, Liza has $1633 - $70 = $1563 left in her account.

First Store:50000(.10) = 5000. 50000 - 5000 = 45000 pounds. Second Store:45000(.20) = 9000. 45000 - 9000 = 36000 pounds.
