Answer:
Step-by-step explanation:
Let x represent the original price of the jacket.
At a clothing store, jackets are on sale for 30% off. This means that x will be reduced by 30%. There is also
Sales tax of 5%. This means that x would increase by 5%. The net change in price of the jacket in terms if percentage will be 30% - 5% = 25%.
Therefore,
The total cost of the jacket will be the original price - 25% of the original price. The expression becomes
Let y represent the total cost
y = x - 0.25x = 0.75x
