kramer

Answer:

 Lia collects $ 37.5 ,  Phil collects  $50.3  and Cam collects dollars $ 112.5 .

Step-by-step explanation:

Let us assume that the dollar collect by the Lia be x .

As given

Lia, Phil, and Cam collect a total of 200.30 dollars for a holiday fundraiser.

Phil collects 12.80 dollars more than Lia.

Phil collects dollars = 12.80 + x

As given

Cam collects 3 times as much as Lia.

Cam collects dollars = 3x

Than the equation becomes

x + 12.80 + x + 3x  = 200.30

12.80 +  5x  = 200.30

5x =  200.30 - 12.80

5x = 187.5

x = \frac{187.5}{5}

x = $ 37.5

Thus

Lia collects dollars =  $ 37.5

Phil collects dollars = 12.80 + 37.5

                                = $50.3  

Cam collects dollars = 3 × 37.5

                                  = $ 112.5

Therefore the  Lia collects $ 37.5 ,  Phil collects  $50.3  and Cam collects dollars $ 112.5 .

Ronnie misses the school bus 1 out of every 30 school days. He sets up the proportion 1/30=180/x to predict how many days he wil
bija089 [108]

Answer:

1/30=x/180

Step-by-step explanation:

The way that Ronnie wrote his proportion is wrong since 180/x is saying that he will miss 180 days of school. The fraction 1/30 means that he would miss 1 day out of 30 days, which is correct. But the fraction 180/x would mean that he is missing 180 days of school, which is wrong.

Solving:

1/30=x/180

180/30=6

1 x 6 = 6 days

He will miss 6 days of school in 180 days.
