The manufacturerâs suggested retail price (msrp) of a certain item is $60. store a sells the item for 20 percent more than the msrp. the regular price of the item at store b is 30 percent more than the msrp, but the item is currently on sale for 10 percent less than the regular price. if sales tax is 5 percent of the purchase price at both stores, what is the result when the total cost of the item at store b is subtracted from the total cost of the item at store a? a. $0b. $0.63c. $1.80d. $1.89e. $2.10

C. $1.80

Step-by-step explanation:

Given:

MSRP of a certain item = $60

Percentage of Selling by store A = 20%

Percentage amount will be =

Sales tax = 5% on purchase price

Amount of sales tax =

Total Cost of item at Store A is MSRP of a certain item plus Percentage amount of selling the item plus Amount of Sales tax.

framing in equation form we get;

Total Cost of item at Store A =

Also Given:

Percentage of Selling by store B = 30%

Percentage amount will be =

Regular price of item at store B =

Percentage of discount of item at store B = 10% on regular price

Amount of discounted item at store B =

Now regular price of item with discount at store B will be equal to Regular price of item at store B minus Amount of discounted item.

regular price of item with discount at store B =

Sales tax = 5% on purchase price

Amount of sales tax =

Total Cost of item at Store B is regular price of item with discount at store B plus Amount of Sales tax.

framing in equation form we get;

Total Cost of item at Store B =

The result when total cost of the item at Store B is subtracted from the total cost of the item at Store A  = $73.2 - $75 = $1.80.

Hence the result is $1.80.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
