A student received a coupon for ​%18 off the total purchase price at a clothing store. Let y be the original price of the purchase. Use the expression below for the new price of the purchase. Write an equivalent expression by combining like terms

Final cost of item = initial price(1 – rate)

Step-by-step explanation:

y(1 – .18) = .82y

Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Price to enter the carnival = $4

Cost of per ride = $0.50

Since , Number of rides = 7

So, Total amount he will spend is given by

Since Option 'C' is to be eliminate as $9 cant be possible if we take $9 as our answer,

then first we subtract $4 from $5 to get the cost of rides

i.e. 9-4=$5

Now, number of rides will be

which is wrong as we have given that he rode only 7 rides , So, Option 'C' is not correct.

Hence, Option 'B' is correct.
