Answer:
One of the texts costs $59.325 and the other costs $33.825
Step-by-step explanation:
This question can be solved by a system of equations:
I am going to call one text x and the other y.
You purchase two supplemental texts on sale for your math course, totaling $93.15.
This means that [tex]x + y = 93.15[/tex]
You can’t remember the cost of each text, but you remember that one text is $25.50 more than the other.
This means that [tex]x = 25.50 + y[/tex]
So
[tex]x + y = 93.15[/tex]
[tex]25.50 + y + y = 93.15[/tex]
[tex]2y = 67.65[/tex]
[tex]y = \frac{67.65}{2}[/tex]
[tex]y = 33.825[/tex]
[tex]x = 25.50 + y = 25.50 + 33.825 = 59.325[/tex]
One of the texts costs $59.325 and the other costs $33.825
