-9(3-r)=45
-27+9t=45
9r=45+27
R=72/9
R=8

Answer:
$225
Step-by-step explanation:
A quarter is made up of 4 months,
If auto insurance is $900 per quarter, the monthly expense would be $900 / 4 = $225
If you turn 9 1/3 in to a decimal and 3 1/2 in a decimal also
9 1/3 = 9.3 and 3 1/2 =3.5
9.3+3.5 =12.8
12.8=12 4/5
