14*15 is 210 which his the entire area. now divide 210/20 you get 10.5 so you will need at least 11 bags
Y= 3(3)–2(3)2+5(3)3
y= 9–2*3*2+5*9
y=9–12+5*9
y=9–12+45
y=42
Is 125 because u need to take the 5 and add 3 on the top
First you need to multiply 36 *$30.22=$1087.92
This gives you the total amount paid
Then subtract 1087.92-900=187.92
This gives you the amount of money you paid in finance charges.
