Mr. Rubio will spend $29.10 in all.
Step-by-step explanation:
Given,
Cost of one burger = $2.75
Cost of one drink = $1.30
Cost of an order of fries = $0.80
Cost of 1 meal = 2.75+1.30+0.80 = $4.85
Members of family = 6
Cost of 6 meals = Cost of one meal * 6
Cost of 6 meals = 4.85*6 = $29.10
Mr. Rubio will spend $29.10 in all.

Given:
Cost of two donuts and three cookies = $3.30
Cost of five donuts and two cookies = $4.95
To find:
The cost of each donut.
Solution:
Let x be the cost of each donut and y be the cost of each cookie.
Cost of two donuts and three cookies = $3.30
...(i)
Cost of five donuts and two cookies = $4.95
...(ii)
Multiply equation (i) by 2.
...(iii)
Multiply equation (ii) by 3.
...(iv)
Subtracting (iii) from (iv), we get


Divide both sides by 11.


Therefore, the cost of each donut is $0.75.
