Answer:
r = -46/3
Step-by-step explanation:
-3(r+2)=40
Distribute
-3r - 6 = 40
Add 6 to each side
-3r-6+6 = 40+6
-3r = 46
Divide by -3
r = 46/-3
r = -46/3
After 20% reduction the price is $48 which means $48 is only 80% of the original price...so let x= original price
<span>48=.8x </span>
<span>60=x </span>
<span>it was $60
