Miranda wants to buy a pair of heels she saw online. She saved money for 3 months. Her sister heard that she was sad and gave her $50 for her to buy the heels. If she paid $260 in total for the heels, how much money did she save per month?
First find the total amount of money she saved: $260 - $50 = $<<260-50=210>>210
Then divide that number by the number of months she saved to find the amount she saved each month: $210 / 3 months = $<<210/3=70>>70/month
#### 70
