Answer: $1.80 and $11.40
Explanation:
We know that Chris was short on cash by $1.20, but we need to create an equivalent percentage.
95% + 15% = 110% (how much does it cost)
110% - 110% (how much he had) = 10% (amount short) = $1.20
10% = $1.20
100% (how much he had) = $12.00
Mouse = 95% of $12.00 (how much he had) = $11.40
Mouse pad = 15% of $12.00 (how much he had) = $1.80
Check your work:
$1.80 (Mouse pad) + $11.40 (Mouse) = $13.20
$13.20 - $12.00 = $1.20 (amount short)
We were correct!
Final Answer: $1.80 and $11.40
