vladimir2022 [97]

Hi There!

-----------------------------------------------------

Baseball Bats:

43 x 0.45 = $19.35 as the amount off.

43 - 19.35 = $23.65 with the discount.

23.65 x 2 = $47.3 for two bats.

-----------------------------------------------------

Glove:

28 x 0.25 = $7 as the amount off.

28 - 7 = $21 with the discount.

-----------------------------------------------------

Together:

21 + 47.3 = $68.3 as the total before taxes.

-----------------------------------------------------

With Taxes:

68.3 x 0.055 = $3.7565 as the tax amount.

68.3 - 3.7565 = $64.5435

-----------------------------------------------------

Answer:

Not Rounded: $64.5435

Rounded: $64.54
