Leila has $134, and Dianne had $180. After both of them spent an equal amount of money shopping, Dianne had 3 times as much money as Leila. How much did each of them spend?

They spent $111 on shopping

Step-by-step explanation:

Let the amount they spent be 'a'

Leilas amount = $134

Diannes amount = $180

After they spent same amount on shopping dianne had 3 times as much money as Leila

180 - a = 3 (134 - a)

180 - a = 402 - 3a

3a - a = 402 - 180

2a = 222

a = $111

They spent $111 on shopping
