In the equation the $50 would be the start up or in other words the y-intercept
Answer:
7.50
Step-by-step explanation:
he will save $7.50
50 x 0.15 is 7.50
The answer is 14.
I-14I change to positive in this case.
The expression that will help him to determine the total cost is as follows:
y = 60 + 4x
<h3>How to construct an expression?</h3>
He signed up to provide snacks for his daughter and her school group's camping trip.
He found a package of granola bars in bulk for $60 that he thought would be enough for everyone for a few days.
He also wanted to buy some boxes of fruit snacks, which were $4 each.
The number to buy and the total cost can be expressed as follows:
let
y = total cost
x = number of boxes of fruit juice.
Therefore, the expression that will help him to determine the total cost is as follows:
y = 60 + 4x

Answer:
3.) Choice B
4.) Choice A
Step-by-step explanation:
<em><u>Question #3:</u></em>
You can find the equation by doing the y divided by the x and you'll get 4 every time so that's why it's Choice B.
<em><u>Question #4:</u></em>
A proportional equation is always a straight line that goes through the origin. So the answer is Choice A because it's the only one without a y-intercept because if the equation had a y-intercept it wouldn't go through the origin. For example, Choice B would go through (0,5) and Choice C would go through (0,-1) but we need it to go through (0,0).
