Answer: R = {4, 5, 7, 19}
<u>Step-by-step explanation:</u>
Domain represents the x-values.
Range represents the y-values.
Insert the values of the domain into the given equation.

Bananas cost: $0.25
Apples cost: $0.30
4b+5a=2.50
10b+3a=3.40
You multiply the equations by the variables so they can cancel out. For example the first one by 3 and the second by 5 so you have
12b+15a=7.50
50b+15a=17
Subtract them and end up with
-38b=-9.5
solve: b=0.25, substitute b in any equation and get a=0.30
