The boys bought 5 packages of hot dogs for 22.50 at the store.if each package of hotdogs had 9 hotdogs in each, what is the cost of each hotdog

the answer is B

Step-by-step explanation:

you take 9x5 and you get 45. you take your 22.50 and divide it  by your 45

Step-by-step explanation:

The perimeter is twice the sum of the lengths of adjacent sides. If we let w represent the width, then 2.5w can represent the length. The perimeter (in centimeters) is ...

  P = 2(L +W)

  84 = 2(2.5w +w) . . . . . substitute known values

  84 = 7w . . . . . . . . . . . . simplify

  12 = w . . . . . . . . . . . . . .divide by 7

  L = 2.5w = 2.5×12 = 30

The width is 12 cm; the length is 30 cm.
