What does find the constant rate of change mean?

1 answer:

7 0

The change of the cost changes when the pounds of ham changes. When the pounds of ham is 0, it costs 0 dollars. When the pounds of ham is 3, it costs 12 dollars. The cost changes consistently with the pounds of ham. They change together. Every time the pounds of ham goes up by 3, the cost goes up by 12.

You have quarters and dimes that total $2.80. Your friend says it is possible that the number of quarters is 8 more than the num

Answer:

Step-by-step explanation:

d = number of dimes

2.80 = 0.1d + 0.25 (d + 8 )

2.80 = 0.1d + 0.25d + 2 Combine like terms

2.80 = 0.35d + 2 Subtract 2 from both sides

0.80 = 0.35d Divide both sides by 0.35

d ≈ 2.29

No, it's not possible to have more quarters than dimes when the total is $2.80 because it's not possible to have part of a dime.
