A store sells four-packs of permanent markers in assorted colors for $3.19 per pack. All spiral-bound notebooks, whether wide-ruled or college-ruled, sell for $1.20 each. Cleo buys x packs of markers, y wide-ruled notebooks, and z college-ruled notebooks. The store charges a 6% sales tax on Cleo’s total bill. Which expression represents the amount Cleo must pay after taxes?

A.
3.19x + 1.20y + 1.20z + 1.06
B.
3.19x + 1.20yz + 1.06
C.
1.06(3.19x + 1.20yz)
D.
1.06(3.19x + 1.20y + 1.20z)

Answer:

A

Step-by-step explanation:

1 Pack of Permanent Markers cost $3.19

Wide-ruled and college-ruled notebook both is $1.20 per piece

6%=0.06

6%*1.06=0.06

or

(A trick) 100%+6%= 1.06

1.06 is the issued tax and that need to be added.

So not after we have eliminated C and D we look at A and B

Why 12.06yz won't work because of we solve wit order of operation all of these digits will be multiplied.

It's true that products given quantities y and z are the same price, but we can not multiply them.

Though we can take advantage of them being same price and y and z are variables for the same category "quantity" we can do

(1.20*(y+z))

But this option is not given so we do each one separately, so A
