Answer: Therefore, the price of a wrap is Rs 92.2 and the price of a milkshake is Rs (92.2 + 7) = 99.2.
Explanation:
Let's assume the price of a wrap is x (in Rs).
According to the given information, a milkshake costs Rs 7 more than a wrap. So, the price of a milkshake would be x + 7 (in Rs).
The group buys 8 milkshakes and 2 wraps. Since they bought 8 milkshakes, the total cost of milkshakes would be 8 * (x + 7) = 8x + 56 (in Rs).
Similarly, the total cost of wraps would be 2x (in Rs).
The total cost for the lunch is given as Rs 978.
So, we can set up the equation:
Total cost of milkshakes + Total cost of wraps = Total cost of lunch
(8x + 56) + (2x) = 978
Combining like terms:
10x + 56 = 978
Subtracting 56 from both sides:
10x = 922
Dividing both sides by 10:
x = 92.2
