Lia phil and cam collect $200.30 for a fundraiser phil collects $12.80 more than lia. cam collects 3 times as much as lia. how much does each person collect?

This is an easy question on application of algebra.

First, you should write down all the facts you know.

   (P for Phil, L for Lia and C for Cam.)

   P + L + C = 200.30

   P = L + 12.80

   C = 3L

Second, you should find common letter in those equations.

   In this case, it's L.

   So, you should subtitute P = L + 12.80 and C = 3L to P + L + C= 200.30.

   Then you will get (L + 12.80) + L + 3L = 200.30

Third, then you can solve it using basic algebra.

   (L + 12.80) + L + 3L = 200.30

=  5L + 12.80 = 200.30

=  5L = 187.50

=  L = 37.5

Lia collected 37.5.

Fourth, You just subtitute L to other equations.

Then you will get C and P as well.

Hope it helped!

the correct answer is 1: 2

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
