Question

alice and jesse went to a cafe. alice paid $13.25 for 2 hot teas, 1 orange juice, and 3 chocolate milks. she knows the orange juice is twice the price of the hot tea. jesse bought 1 hot tea and 1 orange juice. he received $1.25 in change from a 5 dollar bill. what is the price of one chocolate milk at the cafe?

Answer 1

//Okay, for this I'll say hot tea = x, orange juice = y and chocolate milk = z.
2x + y + 3z = 13.25
2x = y
5 - 1.25 = 3.75
x + y = 3.75

Therefore,
x + (2x) = 3.75
x = 1.25
y = 2.50
z = 2.75

A chocolate milk costs $2.75
