Explanation:
We can start by assuming that the price of the meal is x dollars. Then, we know that:
15% of x is equal to $4.89
18% of x is equal to $5.87
20% of x is equal to $6.52
We can set up three equations using these statements:
0.15x = 4.89
0.18x = 5.87
0.20x = 6.52
Solving for x in each equation, we get:
x = 4.89 / 0.15 = 32.60
x = 5.87 / 0.18 = 32.61
x = 6.52 / 0.20 = 32.60
Since all three equations give us a value of x that is very close to 32.60, we can assume that the price of the meal was $32.60, rounded to the nearest cent.
