who spent more on tax?

$42.26

Tom pays more since 7% is greater than 4%

Step-by-step explanation:

7% Tax = 1+0.07=1.07x

22*1.07= $23.54

4% Tax = 1+0.04=1.04x

18*1.04= $18.72

- Now Add

23.54+18.72= $42.26

$42.26

Tom spent more on tax ($1.54 vs his cousin's $0.72)

Work Shown:

Tom: $22 x 1.07 = $23.54

tax spent = 22 x 0.07 = $1.54

Cousin: $18 x 1.04 = $18.72

tax spent = 18 x 0.04 = $0.72

Total= $23.54 + $18.72 = $42.26
