Answer:
13.50=0.75(x+10)
Step-by-step explanation:
From the options given, it seems the price of either of Sandals or sneakers is given as 10 and the other is x
If Price of Sandals or sneakers=x
And the price of the other one is 10
Total price=(x+10)
25% discount is given
So she will pay 75% of the total cost
75%=0.75
Total cost =$13.50
She would pay 75% of (x+10)
Which is
0.75(x+10)=13.50
13.50=0.75(x+10)
