Joel is training for a marathon. Right now he can run 3 miles. In two weeks he plans on running 5 miles, in four weeks he plans on running 8 miles.

If Joel's mileage continues growing with the same pattern, how many miles will he be running in 10 weeks?

A) 15
B) 17
C) 23
D) 26

c) 23

Step-by-step explanation:

The relationship between the amount of growth per 3 weeks is proportional.

If you made a table it would look similar to:

x      |          y  | Rate of Change

1      |          3  | +0

2     |          5  | +2

4     |          8  | +3

6     |         12  | +4

8     |          17 | +5

10    |         23 | +6

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

y -5 = (-1/4)(x + 8)
