Question

One of your friends gives you $10 for a charity walkathon. Another friend gives you an amount per mile. After 5 miles, you have raised $13.50 total. Write an equation in slope-intercept form that represents the amount y of money you have raised after x miles.
Y=?

Answer 1

Answer:

y=0.70x +10

Step-by-step explanation:

Answer 2

One of your friends gives you $10 for a charity walkathon -- this is your beginning amount.

Another friend gives you an amount per mile -- you will need to calculate this value.

After 5 miles, you have raised $13.50 total --

-- Since one friend gave you 13.50 to give you the amount earned by walking the 5 miles

-- 10.00 = $3.50

-- Since you walked 5 miles, divide 0.70 per mile earned.

So, an equation that represents the amount of money earned is: y = 10.00

This is in slope-intercept form; the slope is $0.70 and represents the amount of money earned per mile

and the intercept is $10.00 and represents the initial amount of money that you were given
