Math question plz help wit it plzz?
8 + 2.5(8) = cost

8 + 20 = 28

It will cost $28.00
Reply:Should be 8+2.5*8=28
Reply:cost ($) = 8 + 2.5f (where f = number of flowers)

cost ($) = 8 + (2.5 x 8)

cost ($) = 8 + 20 = $28
Reply:8 + 2.5f = total cost



since the given is 8 flowers,,



8 + 2.5(8) = 28 $
Reply:28. If f represents the # of flowers, and 8 is the #... then the equation reads--- 8 + (2.5 * 8).... 8 + 28 = 28
Reply:8+2.5f

f=8

8+2.5(8)=8+20.0

$28.00
