jacob is ordering custom t-shirts for his soccer team. long-sleeved shirts cost $15 each and short-sleeved shirts cost $10 each. jacob can spend at most $250 and he wants to order at least 20 shirts.

let x represent the number of long-sleeved shirts. let y represent the number of short-sleeved shirts.

what are all inequalities that represent constraints for this situation?

x+y≤20

x+y≥20

15x+10y≥20

15x+10y≥250

x+y≤250

15x+10y≤250

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
