densk [106]

Answer:2.19 monthd

Step-by-step explanation:

Cris borrowed money from her brother 6 months ago. She now owes him 56.50

Let x= original money borrowed from her brother 6 months ago

She has not borrowed and she is paying 15.75 on her debt each month for the last 6 months. This means in the past 6 months,she has paid 15.75×6= 94.5

She now owes him 56.50. This means original money,x-56.50 =94.5

x = 94.5+56.50=151

If she now increases her monthly payment to 25.75, let the number of months be y, she will pay 25.75y in y months

25.75y =56.50

y =2.19 months
