Question

At the school cafeteria, the cost of one milk is $0.50. The total cost of 5 turkey sandwiches and 4 milks is the same as the total cost of 4 turkey sandwiches and 8 milks.

Answer 1

are you trying to find the cost of turkey sandwhich?

Answer 2

Sorry for the missing information, parent trying to re-learn to help my son.
I need to:
a. Write an equation that can be used to find the cost of a turkey sandwich. Explain what each expression or value represents in the equation.

b. Use the equation you wrote in part a. to find the cost of a turkey sandwich. Explain how you solved the equation.

I *think* the equation (inequality) should be:
T= turkey sandwich

5t + 4(0.50) = 4t + 8(0.50)
5t + 2.00 = 4t + 4.00

Is that right?

Answer 3

correct

Answer 4

bingoo

Answer 5

Yay! This stuff is not easy, I have been out of school for 30 years :/

Answer 6

practice makes perfect :D

Answer 7

It was no easier 30 years ago:P

Answer 8

No, it wasn't. Math was never my subject.

Trying to solve this now, but not sure of how to. So let me run this by you...

5t+2-4t=4t+4-4t ??

Answer 9

subtract 4t from both sides then add the 2. gotta believe in yourself, you already know how to do it!

Answer 10

subtract the 2*

Answer 11

So, t+2 = 0 +4
-2 -2

t = 2

Answer 12

correct

Answer 13

exactly.
check your work by plugging it back in.
5t+4(.5) = 4t+8(.5)
if t = 2 then they should be the same..
5(2)+2 = 4(2)+4
10=10

Answer 14

Thank you all very much! I probably do know how to do this stuff but I needed a little moral support. I appreciate your time :)
