Answer:
X = 20 and Y = 5
Step-by-step explanation:
you're supposed to substitute the numbers it so the problem x * 2 also means 10 * 2 because x = 10 and y * 1 also means 5 * 1 because y = 5
59 because if you do 3x8 that equals 24 and then you do 35+24 that equals 59
So if he wants to have more then 100 in his bank then what i would do is take 100 from 460 and you get 360 then divide that by 45 and you get 8 but as said before he wants more then 100 so he would be able to pay 7 months in a row and have over 100 in his bank account still
(new -original)/original * 100
(36-20)/20 * 100
16/20 * 100
.8*100
80
