serious [3.7K]

Answer:

The meal consist 11 mozzarella sticks and 6 pizza rolls.

Step-by-step explanation:

We are given the following in the question:

Calories in mozzarella stick = 90

Calories in pizza roll = 80

Let x be the number of a mozzarella stick and y be the number of pizza rolls.

Total calories in meal = 1470

Thus, we can write the equation:

90x + 80y = 1470

There are five more mozzarella sticks than pizza roll.

Thus, we can write the equation:

x = y + 5\\x-y = 5

Solving the two equations, we get,

90x+80y+80x-80y = 1470 + 400\\170x = 1870\\x = 11\\y = 11-5 = 6

Thus, the meal consist 11 mozzarella sticks and 6 pizza rolls.
