The class of 2015 decides to start a T-shirt company. After initial expenses of $280, the purchase each t-shirt for $3.99. They sell each t-shirt for $10.99. how many must they sell to break even?

Answers

$280=budget

10.99-3.99= $7 profit made with each shirt

$280/7= 40

Therefore the class must sell at least 40 t shirts to break even
70 bc, if u round up 3.99 it equals 4. then 4x70=280 the number you want. and if you round up 10.99 to 11 its 770 so you would have 490 left over to buy more

T is 71 degrees. We know this because the area of a triangle is 180 degrees, you add the angles given 27+82 which equals 109 then subtract that from 180 to find the missing angle “T” 180-109=71

Answer:

71 degrees

Step-by-step explanation:

The angles in a triangle add to 180 degrees, so

∠M + ∠A +∠T = 180

We know ∠M is 82 degrees, and ∠A is 27 degrees, so we can substitute them in.

82+27+∠T=180

109+ ∠T=180                      Combine like terms by adding 82 and 27

109-109+ ∠T=180-109        Subtract 109 from both sides to get ∠T by itself

∠T=71

So, the m∠T is 71 degrees
