Question

Suzanne bought a sofa for d dollars and paid 8% sales tax. Write two different expressions that represent the total number of dollars, including tax, that Suzanne spent, and show or explain why the expressions are equivalent.

Answer 1

The total money spent by Suzanne for sofa is =
`c=d+0.08d` or
`c=d(1+0.08)`

Explanation:

Let the overall cost be represented by = c

Cost of the sofa is = $ d

Sales tax paid for the sofa is = 8%

So, this becomes 8% of d = 0.08d

So, the total money spent by Suzanne for sofa is =

`c=d+0.08d` or
`c=d(1+0.08)`
