Marcelino bought balloons to sell at lunches to raise money for charity
Arada [10]

Answer:

<u>Marcelino will have $7.50: his costs are more than his profits. </u>

Step-by-step explanation:

22.50 + 7.50 + 15.00

In total Marcelino spent $45 to make these balloons.

He wants to sell each balloon for $1.25.

If he sells the 30 balloons he bought for $1.25 he will make:

30 * 1.25 = $37.50... okay he made some money, BUT he spent $45 dollars for the items.

45 - 37.50 = $7.50, Marcelino made no profit... he still needs to make $7.50 to pay off his own costs.

Find the equation of the linear relationship.
rosijanka [135]

Answer:

y = -3x + 150

Step-by-step explanation:

2 points on the graph:

(30, 60) and (40, 30)

Slope:

m=(y2-y1)/(x2-x1)

m=(30 - 60)/(40 - 30)

m= (-30)/10

m= -3

Slope-intercept:

y - y1 = m(x - x1)

y - 60 = -3(x - 30)

y - 60 = -3x + 90

y = -3x + 150
