Mrs. Jolley is thinking of buying solar panels to put on the roof of her new house. The sunny solar company told her that for every 2 panels, she will save $60 on her electric bill. (a) Draw a model or make a visual representation for the ratio for the panels to the money that she will save on her electric bill.

(b) Write the ratio of panels to money saved as a reduced fraction.

y = $30x ;

1 : $30

Step-by-step explanation:

Given that :

$60 is saved in electricity bill for every 2 panels

Model, y

Amount saved, y = amount saved per panel * number of panels

Let number of panels = x

Hence, total amount saved, y ;

y = $30x

Ratio of panels to money saved :

Number of panels : amount of money saved

2 : $60

1 : $30

Hence, $30 is saved in cost of electricity bill per 1 solar panel purchased.

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.
