To find the amount that Franklin financed, you will calculate the amount he put down and subtract that from the original price because that is what he still owes.
0.2 x $4500 = $900
$4500 - $900 = $3600.
Porter financed $3600.
You also multiply 0.8 x $4500 because this represents the part out of 100% he still owes. You will get the same answer this way.
2x+3(0)=18 2x=18 x=9
2(0)+3y=18 3y=18 y=6
58-10=48 = 1 hour
48/12= 4 = 4 hours
Aaron was the sitter for 5 hours
