To find the total amount Leo should give, simply find the 20% of his bill then add it.
Total cost = $45.90 + ($45.90 × 0.20)
Total cost = $45.90 + $9.18
Total cost = $55.08
Therefore, Leo should give $55.08 in total to leave a 20% tip.
You subtract 7% from 32=29.76
Then you subtract 8% from 29.76=27.379
