A nursery owner buys 5 panes of glass to fix some damage to fix some damage to his greenhouse. The 5 panes cost ​$11.75. ​Unfortunately, he breaks 2 more panes while repairing the damage. What is the cost of another 2 panes of​ glass?

Cost of single pane = 11.75 / 5 = $2.35

Cost of 2 extra panes = 2*2.35 =$4. 7

The cost for 2 more glass panes is $4.70

Step-by-step explanation:

1. Fist divide 11.75 by 5 to find out how much one pane costs, you should get 2.35.

2. Next multiply 2.35 by 2 to find out how much it is for 2 more glass panes.

Then you will get our answer ($4.70)

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
