Step-by-step explanation: 7 1 16 15
Meal Alone = 393.16
Tax 393.16 × 0.0625 = 24.57 Recall 6.25% = 6.26 / 100 = 0.0625
Tip 393.16 × 0.18 = 70.77 Recall 18% = 18 / 100 = 0.18
Add up the three values = 488.50 Total
an easier way to do this !!!!!! use the distributive rule
393.16 ( 1 + 0.0625 + 0.18)
393.16 ( 1.2425)
Total = 488.5013 or $488.50
