Answer:
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.
3/5(30x - 15) = 72
18x - 9 = 72 <==== this is one
3(6x - 3) = 72 <== this is one
18x = 81 <== this is one
x = 81/18
x = 4.5 <== this is one
