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.

Isabella has a board that is 5.24 feet long and 1.34 feet wide.

Masteriza [31]

Answer:

Length of 1 piece= Length of total divided by 8

Step-by-step explanation:

Length of total= 5.24 feet long

Width of total= 1.34 feet wide

Width is divided by 1 line so, there are 2 parts.

Width= 1.34 divided by 2

Width= 0.67 feet wide

Length is divided by 7 lines, so there are 8 parts.

Length= 5.24 divided by 8

Length=0.655 feet long

They are asking for formula to find the length of each piece

Length of 1 piece= Length of total divided by 8

Hope that helps!
