Okay, so you need to calculate 2 separate prices for each of these items. Finding the sale tax is pretty simple: Just multiply whatever the percentage given is (0.07), and then add that to the original value.
Original Value + (Original Value x Tax) = Total Value
A. 10.77 + (10.77 x 0.07) = 10.77 + 0.7539 = 11.52
B. 2.09 + (2.09 x 0.07) = 2.09 + 0.1463 = 2.24
C. 0.75 + (0.75 x 0.07) = 0.75 + 0.0525 = 0.80
Now to finish the problem, add all your newly found values together for the total amount of money Zoe spent: 11.52 + 2.24 + 0.80 = 14.56.
Zoe must pay 14.56 for the items she purchased, including tax.
