Charles went to the hardware store and purchased a

hammer, a pair of gloves. a bag of nails. and a shovel.
The total cost includes the cost of the items and the state
sales tax. The equation T = 1.065x can be used to
calculate the total cost of his purchase, T. where x
represents the pretax subtotal of his purchase.
Part A: In the equation T = 1.065x, what does the number
"1.065" represent?

It represents $106.50, which is the total cost for the purchases made by Charles.
It represents the 10.65% of state sales tax that is added to the pretax cost of the purchase.
It represents the $1.65 state sales tax that Charles had to pay for every $10 he spent in the hardware store
It represents 106.5%, so when multiplied by the pretax cost of the purchase, the resulting product is the total cost, including state sales tax.
