1 TREES A tree in front of Marcel's house has a shadow
12 feet long. Marcel's shadow
is 3 feet long. If Marcel is 5.5
feet tall, how tall is the tree?
h ft

22ft tall

Step-by-step explanation:

We can solve by creating a ratio.

We then solve for x by cross multiplying.

3x = 66

x = 22

Using $285 for 3 days and $510 for 6 days, we get

285/3 = 95

510/6 = 85

which seem to be different rates per day, but we need to look at it differently.

For 6 days, you pay $510.

For 3 days you pay $285.

The difference between those two rentals is 3 days and $510 - $285 = $225.

The rental amount due to teh daily rate is $225.

$225/3 = $75.

For each day you rent, you must pay $75.

The rest of the payment is a one-time fee for the rental.

3 days due to daily rental fee: 3 * 75 = 225

Problem tells us that for 3 days, it's $285.

$285 - $225 = $60

One-time fee = $60

y = 75x + 60

f(x) = 75x + 60
