Answer:
The answer is 57.83
Step-by-step explanation:
find 8% of 45.90 and add 18% of 45.90 and add them together.
8%*45.90=3.67
18%*45.90=8.26
Add, 45.90+8.26+3.67
The final price of your meal is 57.83
Let, that number = x
It would be: x * 0.65 = 52
x = 52 / 0.65
x = 80
So, that number and your answer is 80
18 is 45% of 40
45%/100 = 0.45
0.45*40=18
