Answer:
D. 1.06(3.19x + 1.20y + 1.20z)
Step-by-step explanation:
Since marker packs are 3.19 each, the cost of the marker packs she buys can be represented by 3.19x.
All spiral notebooks are 1.20 each, so the cost of the wide ruled notebooks can be represented by 1.20y.
The cost of the college ruled notebooks can be represented by 1.20z.
In the expression, all of these terms have to be added together and multiplied by 1.06 to calculate the sales tax.
So, the expression will be 1.06(3.19x + 1.20y + 1.20z)
