Molly McGee is painting her room violet. The 15 gallon bucket of purple paint that she currently has is 30% red paint and 70% blue paint. This shade of violet is more red, and
so Molly will need paint that is 40% red paint, and thus 60% blue paint. How many
gallons of red paint should she add to her current bucket in order to be able to paint her
room violet?

1.5 gallons of red paint

Step-by-step explanation:

finding 10% of 15 gallons:

15 x 0.1 = 1.5

If Molly needs to go from 30% - 40% of red paint and 1.5 gallons is equal to 10%, then Molly needs to add 1.5 more gallons of red paint to her current bucket in order to be able to paint her room violet.

dont think so

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.
