7. you and a friend are paid $38.25 for doing yard
work. you worked 2.5 hours and your friend
worked 2 hours. you split the money according
to the amount of time each of you worked. how
much is your share of the money? explain.

Amount earned by me and my friend will be $21.25 and $17.

Step-by-step explanation:

Total money which me and my friend have earned is = $38.25

Work done by me = 2.5 hours

Work done by my friend = 2 hours

So the ratio of me and my friend =

Now we have to divide the amount earned in the same ratio.

Amount earned by me = 38.25 ×

                                     = 38.25 ×

                                     = 38.25 ×

                                     = $21.25

Therefore, amount earned by my friend = (38.25 - 21.25) = $17

Hence, amount earned by me and my friend will be $21.25 and $17.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
