We can represent the cost of the notebooks with by saying 0.75n, and the cost of the pens by saying 0.55p.
0.75n+0.55p will be the total cost before tax. Now, we need to add on tax. Tax will be 0.0625 times the total amount, so we can represent the cost by saying
(0.75n+0.55p) + 0.0625(0.75n+0.55p), so the answer is B.
Answer: 25 as a exponent is
.
Step-by-step Explanation: To write a exponent, you figure out the main number and how many times the main number is repeating.
Ex: 91x91x91x91x91x91x91
Main number: 91
Repeating how many times: 7
Final answer:
