Answer:
391
Step-by-step explanation:
Since the rent increased by 15%, multiply R by 1.15 like this: 1.15R
The rent increased by $51, so add 51 to R like this: R + 51
These equations have to be equal to each other
1.15R = R + 51
Subtract R from both sides
1.15R = R + 51
- R - R
0.15R = 51
Divide both sides by 0.15 to isolate the R variable
0.15R/0.15 = 51/0.15
R = 340
This means Cody's current rent is $340
To find the rent for next year, add 51 to that number
340 + 51 = 391
