5 p |
7 p |
2 p |
Difference in the amounts between Lynn and Jade
= 7 p - 5 p
= 2 p
Since both Lynn and Jade spent an equal amount, the difference in the amounts that Lynn and Jade had at first and in the end remains unchanged.
2 p = 16
1 p = 16 ÷ 2 = 8
Amount that Jade had left
= 5 p
= 5 x 8
= $40
Answer(s): $40
