For a school fundraiser, Elena will make T-shirts. She will order T-shirts and print graphics on them. Elena must spend $349 on a printing machine and $4.80 per shirt for the blank shirts, ink, and other supplies.

a. Complete the table giving the total cost Elena will spend to make each specific number of T-shirts.

number of shirts cost in dollars
20
40
60
b. Write an expression for the cost of making n T-shirts.

c. What is the maximum number of T-shirts Elena can make with a budget of $1,000?

a. $445, $541, $637

b. $349 + n * $4.80

c. 135

Step-by-step explanation:

a.

number of shirts | cost in dollars

20  |  $349 + 20*$4.80 = $445

40  |  $349 + 40*$4.80 = $541

60  |  $349 + 60*$4.80 = $637

b.

Cn = $349 + n * $4.80

c.

$1000 = $349 + n * $4.80

n * $4.80 = $1000 - $349

c * $4.80 = $651

c = $651 / $4.80 = 135.625

Maximum number of shirts with a budget of $1,000 is 135.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
