D(x)=1375-110x
when it reaches 0 it has reached destination
0=1375-110x
add 110x to both sides
110x=1375
divide both sides by 110
x=12.5
answer is 12.5 hour

Georgia ,a florist,charges $10 per flower bundle plus a$15 delivery charge per order what is the slopes​
andrew11 [14]

Answer:

  • <em><u>The slope is $ 10 per flower bundle.</u></em>

Explanation:

The <em>slope</em> of a linear function is the ratio of the change in the dependent variable over the change in the independent variable.

In the problem, the independent variable is the number of flower bundles and the dependent variable is the amount charged.

If you call n the number of flower bundles and c(n) the amount charged per order, the amount charged per order is modeled by linear function:

  • c(n) = 10n + 15

Where, 10 is the amount charged in dolars per flower bundle, and 15 is the delivery charge per order.

Then, for every increment in the number of flower bundles (n) the amount charged will increase in $ 10. That is the slope

  • slope = $ 10 / flower bundle.
