Answer:
$149.50
Step-by-step explanation:
M varies directly as D
M ~ D
M = KD
Where:
M = money earn
D = Driveway
K = assumed constant
Therefore
M = KD
$80.50 = k * 7
K = $80.50 / 7
K = $ 11.50
To know how much he earns if he shoves 13 drive way, we repeat the relationship.
That is:
M = KD
M = $11.50 * 13
M = $149.50
He makes $149.50 after shoving 13 driveways

Step-by-step explanation:
34.59*0.15=5.1885
The following pictures should explain well enough how to solve this would take to long to write out the end answer however are x=-12.5 and y=34.75 the steps are the following pictures Hope this helps!=)
8.5 minutes per mile is equivalent to
17 minutes
----------------
2 miles
and the reciprocal of that is
2 miles
-----------
17 min
Now multiply 26.2 miles by
17 min (17 min)* (26.2 mi)
------------ , obtaining ---------------------------
2 miles 2 mi
This simplifies to (17)(26.2)/2 minutes = 222.7 minutes,
or
222.7 minutes 1 hr
-------------------- * ------------ = 3.7 hours
1 60 min
