Step-by-step explanation:
given:
$12.50- the price of the tshirts
40- the tshirts they have sold
$850- the raise they need
solve:
$12.50 × 40 = $500 (the price of tshirts and tshirts they have sold)
$850 - $500 = $350 (the raise they need and the money they have so far from the 40 tshirts they have sold)
$350 ÷ $12.50 = 28 (the money they lack and the price of a tshirt)
answer:
thus, they need to sell 28 more tshirts to have the raise of at least $850
hope this helps, good luck! :)
The internal angle sum of a quadrilateral is :
C. 360°

Answer:
The circumference travels the same distance as the bicycle, 100 m
Step-by-step explanation:
Step-by-step explanation:
width= w
length = l=w+5
Area = l * w
104 =(w+5) * w
w2 +5w -104 =0
(w+13)(w-8)=0
w=13 and w=8
so width =8
length=13
