Question

How much change did Carlotta receive from $40.00 on the purchase of a hair dryer that sold for $29.99 with 8.623% sales tax?

Answer 1

`"Change is "$7.42`

Explanation:

Assumption: Price quoted is pre tax

Note: `8.623% -> 8.623/100`

Tax paid`->8.623/100xx$29.99 = $2.59` to 2 decimal places

So total bill including tax `->$29.99+$2.59=$32.58`

Thus the change is:

`" "$40.00`
`" "underline($32.58)" "larr" subtract"`
`" "$7.42`
