A loaf of bread costs $0.90. Each loaf has 15 slices. How much does each slice of bread cost?

Each slice of bread costs $0.06.

Step-by-step explanation:

To find how much each slice of bread costs, you need to divide the cost (0.90) by how many slices there are (15). When you divide the two, you get 0.06. To check your answer you can do 0.06x15 and that will equal $0.90.

0.9/15=$0.06 per slice

Also what is this 1910 when did a loaf of bread cost 90 cents

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

d is correct
