x > - 9 x < = 2
answer : -9 < x < = 2
Step - by step - explanation
Answer:
your discount would be 25
Step-by-step explanation:
start, first subtract 45 from 60 to find the amount of money taken off from the discount:
60-45
=15
Because 15 dollars have been taken off the original price, you can find the percent of discount by setting up this proportion where x represents the percent of discount:
15/60=x/100
Now, cross multiply and solve for x:
1500=60x
x=25
Therefore, your discount would be 25%.
