Giovanni wants to buy shirts that cost $19.40 each

and sweaters that cost $24.80 each. An 8% sales tax

will be applied to the entire purchase. If Giovanni

buys 2 shirts, which equation relates the number of

sweaters purchased, p, and the total cost in

dollars, y?

A) 1.08 (38.80 + 24.80p) = y

B) 38.80 + 24.80p = 0.92y

C) 38.80 + 24.80p = 1.08y

D) 0.92 (38.80 + 24.80p) = y

y = 1.08 (38.80 + 24.80p)

Option (A) is the correct answer.

Step-by-step explanation:

Cost of 1 shirt = $19.40

Cost of 2 shirts = 2 * 19.40 = 38.80

Cost of 1 sweater = $24.80

Cost of p sweaters = 24.80p

Now sales tax = 8% = 0.08

Total cost of purchases without sales tax = 38.80 + 24.80p

Total Cost of entire purchases with sales tax = (38.80 + 24.80p) + 0.08 (38.80 + 24.80p)

Let the Total Cost of purchases be y.

y = (1 + 0.08) (38.80 + 24.80p)

y = 1.08 (38.80 + 24.80p)

∴ Option (A) is the correct answer.
