Gracie is buying new jackets for her dance squad. She will pay $26.50 for each jacket plus a one-time fee of $15.99 for delivery.
Which equation can be used to find y, the total cost to buy x jackets?

y=26.50x + 15.99

Step-by-step explanation:

Each jacket costs $26.50 so x is the variable to depict how many jackets she is buying because it does not tell us in the question. There is a one-time fee of $15.99 so that is added on to the total to find the total cost which is y.

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

um is there supposed to be a picture?
