Step-by-step explanation:

Girl : Boy

One-fourth : one-eighth

1/4 : 1/8

16 : 7

Then

4/4 : 8/8

64 : 56

Cuz

4x16= 64

8x7= 56

Total 64+56= 120

i think c. but don't trust it.

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
