Question

Oliver is starting a running plan to train for a race. In the first week of his running plan, Oliver will run 14 miles. The plan calls for Oliver to increase his weekly milage by 3.5 miles every week. If Oliver sticks to the plan, how many miles would he be expected to run during his 10th week of the training plan?

Answer 1

49 miles

Explanation:

Let x be equal to the no. of weeks and y be equal to the total amount of miles ran.

Then the equation will be, y = 3.5x + 14

Now to find the amount of miles Oliver ran during the 10th week substitute 10 for x.

So, y = 3.5(10) + 14

y = 35+14

y=49

Answer 2

the answer would be 49 miles

if you let x equal the number of weeks and y equal the total amount of miles, you could set up the equation

y = 3.5x + 14

to find the amount of miles Oliver ran during the 10th week, you would plug in 10 for x, giving you

y = 3.5(10) + 14
y = 35+14
y=49
