1. as a fundraiser the school is holding a breakfast, the bill for the family special of 6 glasses of apple juice and 10 waffles specials is $15.20, whereas the bill for 1 glass of apple juice and 2 waffles specials is $2.90. a. write a system of 2 equations to model this problem. let j stand for the price of a glass of juice and let w stand for the price of a waffle special. b. use the substitution method to solve the system of equations. c. what would the bill be for 1 glass of apple juice and 1 waffle?

Step-by-step explanation:

Let j be the price of one glass of juice and w br the price of a waffle special.

a. We are told that  the bill for the family special of 6 glasses of apple juice and 10 waffles specials is $15.20. We can represent this information as:

We are also told that the bill for 1 glass of apple juice and 2 waffles specials is $2.90. We can represent this information as:

Therefore our system of equations will be:

b. From equation (2) we will get,

Upon substituting this value in equation (1) we will get,

Upon distributing 6 we will get,

Therefore, the price of each waffle special is $1.1.

Let us substitute w=1.1 in equation (2) to find value of j.

Therefore, the price of each glass of apple juice is $0.70.

c. To find the amount of bill for 1 glass of apple juice and 1 waffle we will add price of 1 waffle special and 1 apple juice.

Therefore, the amount of bill will be $1.80.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
