Answer:
$ 8.86 = $2.95 + 0.85 m
Step-by-step explanation:
The above equation can be used to determine the original cost m of the sandwich.
Step-by-step explanation:
Here, the cost of 1 drink = $2.95
The discount in the price of the sandwich = 15%
The total bill of Mitchell = $8.86
Let us assume the original cost of the turkey sandwich = $m
Now, the discount is always applied on the original price.
⇒ 15% of the original price = 15% of m =
So, the discount offered on the sandwich = 0.15 m
Reduced price of the Sandwich = Original Price - Discounted amount
= m - 0.15 m = 0.85 m
Now, Total Bill = Cost of Drink + Reduced cost of sandwich
⇒ $ 8.86 = $2.95 + 0.85 m
Here, the equation $ 8.86 = $2.95 + 0.85 m can be used to determine the original cost m of the sandwich.
