Answer:
10 students in Kindergarten
Step-by-step explanation:
20% is equal to 1/5
1/5 x 50 = 10 or 50 ÷ 5 = 10
To find this answer, first subtract 1,500 from the amount your class raises (16, 600) so you are just left with the 'leftover' money for students to board.
16600-1500= 15100.
Then, divide 15100 into 367 to find out how many can go.
15100/367= 41.1444. Round down to 41.
41 students can attend, and there will be a bit of leftover money. (if you want to figure out how much is left over, multiply 41 by 367, and then subtract 15100 by the product)
$26.20 minimum cost of option 1
$36.68 minimum cost of option 2
Area₁ = Length x Width
A₁ = 80 x 36
A₁ = 2880 in² * this in only one side of the door.
Total Area = A₁ x 2 sides = 2880 = 5760 in² * only good for 1 coating of paint
Total Area to be coated = 5760 x 2 coats of paint = 11,520 in²
1st option - $10 / gallon and 4400 sq. in.
2nd option - $ 7 / gallon and 2200 sq. in
11,520 / 4400 = 2.62 x $10 = $26.20 minimum cost of option 1
11,520 / 2200 = 5.24 x $ 7 = $36.68 minimum cost of option 2
X=a+1/3b+-1/3c. Hope this helps ;)
