Answer:

28

Step-by-step explanation:

Hi! So what we're gonna want to do here is set up a system of equations. Lets say x = regular baskets and y = deluxe baskets. You would set up the system like this:

28x + 24y = 1,188

28x + 13y = 836

So since the number before the x is the same in both equations, we are going to want to cancel that out.

28x + 24y = 1,188

-1(28x + 13y = 836)

----------------

28x + 24y = 1,188

-28x - 13y = -836

Add the two equations together! There will be no x value :)

11y = 352

y = 32... The deluxe basket is going to cost $32

Put the y value into one of the equations to solve for x.

28x + 13(32) = 836

28x + 416 = 836

28x = 420

x = 15... The regular basket will cost $15

Hope this helps!
