Answer:
Erica payed a total of $75
Step-by-step explanation:
Step 1: Determine total lunch cost
Total lunch cost=$60
Step 2: Calculate total sales tax
Total sales tax=tax rate×total lunch cost
where;
tax rate=5%
total lunch cost=$60
replacing;
Total sales tax=(5/100)×60=$3
Total sales tax=$3
Step 3: Cost of tip
Cost of tip=20% of 60=(20/100)×60=$12
Step 4: Total she payed
Total she payed=Cost of tip+total sales tax+total lunch cost
where;
Cost of tip=$12
total sales tax=$3
total lunch cost=$60
replacing;
Total she payed=(12+3+60)=$75
Erica payed a total of $75
