The student council at kensington high school is making t-shirts to sell for a fundraiser, at a price of $12 apiece. the costs, meanwhile, are $6 per shirt, plus a setup fee of $150. selling a certain number of shirts will allow the student council to cover their costs. how many shirts must be sold?

it will take 25 shirts until the council can cover their cost.

Step-by-step explanation:

This is the equation we will use:

0 = 6x - 150

0 means that they did not earn anything but at the same time they covered their cost. $6 is the money they earn because since each shirt cost $6 to produce and they sell it for $12, they only earn $6. -150 is the setup fee it's negative because they still need to cover money.

0 - 6x = -150

-6x = -150

x = 25

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
