Answer:
5.2
Step-by-step explanation:
To find the height of the plant after 7 weeks, we need to find out the equation of the line of best fit and plug in 7 for x. We already have our y - intercept, which is 1, and we have a point on the x axis for which the y coordinate is an integer, (5, 4). Since we already have the y - intercept of +1 we have y = mx + 1. Since this applies to (5,4) we can plug this in to our equation. This is then 4 = 5m + 1. Subtracting 1 from both sides, we get 3 = 5m. Dividing by 5, we receive m = 3/5. Since now we have our slope, we can plug in 7 and find out our answer. Plugging in 7 we receive, y = 3/5 * 7 + 1, which is equal to y = 4.2 + 1. This means that y = 5.2, so 5.2 is our answer.

Answer:
Each car magnet costs $4.95 and each pom-pom costs $0.425
The club spent $495 on 100 car magnets and $85 on 200 pom-poms.
Step-by-step explanation:
I guess that we have to calculate the price of pom-poms and how much money was spent purchasing car magnets and pom-poms.
x + y = 300
2x = y (now we replace y)
x + 2x = 300
3x = 300
x = 100
The club purchased 100 car magnets and 200 pom-poms.
To determine the price of each pom-pom:
($4.95 x 100) + 200P = $580
$495 + 200P = $580
200P = $85
P = $0.425
