Question

Juan took Brooke out for dinner at the Outback. The bill was $40. Juan left a 15% tip. Using 'T' as the total of the bill and the tip, write an algebraic equation that describes this transaction.

Answer 1

so the total of the bill would be 40 + whatever tip he left right?

so he left a 15 % tip......what is 15% of 40?

Answer 2

T=40(0.15)

Answer 3

well no...it would actually be
T = 40 + 40(.15)

if it was just

T=40(.15) that would only be the tip that was left...you have to add in the meal price

so

T = 40 + 40(.15)

Answer 4

but in real life don't you do 40(.15) I dont get where is the other +40 coming from?

Answer 5

which the tip is $6

Answer 6

" The bill was $40. Juan left a 15% tip"

the bill was 40.......that our original cost.......

with a 15% tip...to find that...we do 40(.15) right? this gives us our tip...

our total "T" would be our original cost...+ our tip

so

T = 40 + 40(.15)
