Answer:
$68 option C
Step-by-step explanation:
Lets use equations to show this problem. First, Kyle bought two items, a calculator at a price c and a textbook at a price t and paid $94. So:
c + t = 94 [equation 1] (I will omit $ symbol from now for simplicity)
Then we know that the textbook costs $10 less than the triple of the calculator price. In equation this is:
t = 3c - 10 [equation 2]
Now, replace equation 2 in equation 1:
c + t = c + 3c -10 = 4c -10
4c - 10 = 94
Sum 10 in both sides:
4c -10 + 10 = 94+10
4c = 104
Divide both sided by 4:
4c/4 = 104/4
c = 26
So, calculator price is $26
Replace this value in equaiton 2 (or in equation 1) to find t:
t = 3(c) -10
t = 3*26 -10
t = 78 -10
t = 68
Thus, the textbook costs $68
The correct option is C) assuming you typed wrongly and in the place of the 5 goes a $ symbol.
