Answer:
Tom paid $23.54 while his cousin spent $18.72. Tom spent more on tax $.082 more than his cousin.
Step-by-step explanation:
Tom
Cost of shirt = $22
Sales tax = 7%
Total amount paid = 22 + (7% × 22)
= 22 + 1.54
= $23.54
Tom's cousin
Cost of shirt = $18
Sales tax = 4%
Total amount paid = 18 + (4% × 18)
= 18 + 0.72
= $18.72
Tom spent more on tax as he spent $1.54 as against his cousin's $0.72.
