Question

A blue bike is $14 less than a red bike. The sum of their prices is $300. How much is the red bike?
I thought you would start to solve it by putting the blue bike in terms of red so.. b=14-r and b+r=300 so then 14-r+r=300 thats where i get stuck.. help!!

Answer 1

b is not equal to 14-r
b is r-14

Answer 2

b = r - 14 and b + r = 300

Answer 3

(r - 14) + r = 300

Answer 4

ok i understand now thanks!

Answer 5

Answer 10

R=B+14
R+B=300

Answer 11

\[(B+14)+B=300\]

\[B=150-7=143\]

Answer 14

red bike = $157
blue bike = $ 143

Answer 15

R=B+14=143+14=157
yes i agree

Answer 16

300 - 14 = 286

286 / 2 = 143 (blue bike)

300 - 143 = 157 (red bike)

Answer 17

When you see a statement like A blue bike is $14 less than a red bike.
interpret the "X less than" as -X +
B is 14 less than R
B= -14 + R
which you can re-write as B= R-14

Answer 18

or you can read it as the red bike is $14 more than the blue bike
:)

Answer 19

R=B+14
