Source: Previous question found at brainly
Step-by-step explanation:
A. If the three friends ordered the same meal, we have then:
x = Cost of the meal
Tip = US$ 12
<u>3x + 12 </u>
Total of the meal would be three times the cost of the individual meal, x, plus the tip.
B. Given that x = 7.50, how much was the total cost?
Let's use the equation we wrote in part A.
3x + 12
3 (7.50) + 12
<u>22.50 + 12 = 34.50</u>
