Question

(Help please Medal rewarded and fan)
Jenny and her friends are hungry for dessert. They buy $12.25 worth of cookies and ice cream sandwiches. The ice cream sandwiches costs $1.75 each and the cookies cost $0.75 each. If they buy 11 items total, create a system of equations to represent the problem and find the number of cookies and ice cream sandwiches bought by graphing.

a) name the variables: x is the number of ice cream sandwiches and y is .

b) set up equation for the number of items bought:

c) set up equation for the total spent:

d) Graph the first equation. Y

Answer 1

x is sandwiches and y is cookies?

Answer 2

What is the total number of sandwiches and cookies purchased?

Answer 3

11 in total

Answer 4

So, what is the equation for that?

Answer 5

11= 1.75x+0.75y

Answer 6

No. In this equation you are only concerned with the number of items purchased.

Answer 7

So it would be like 5x+6y=11 since the total is 11 and we dont know for sure how many items were bout?

Answer 8

bought*

Answer 9

Your doing too much work in your head. x = the number of sandwiches, y = the number of cookies.
5 + 6 = 11, that's true, but not relevant to the question.
Sandwiches + cookies = total items purchased.

Answer 10

y = cookies x = ice cream sandwiches
x + y = 11 (number of items bought )
1.75x + .75y = 12.25 (total spent)

I am not good at graphing

Answer 11

Your equations look good.
rewrite the equations in y = mx + b form to make it easier to graph.
In other words, solve for y.

Answer 12

ok thank you very both of yall it helps

Answer 13

sorry that I couldn't help more....gypsy could probably help you with the graphing....she is pretty good at math

Answer 14

Once you have re-written the equations, I can talk you through a simple process of graphing them.
