Yoque borrowed money from her sister. She promised to pay it back in 11 months including an additional 10% of the money she borrowed. If she pays $15 per month, how much money did she borrow? Give me reasons, before answering the question

In 11 months, Yoque will pay a total of $15 x 11 = $165. The amount $165 is 100% + 10% = 110% of the money she borrowed. So, 1% is equal to $165 / 110 = $1.50. Hence, Yoque borrowed $1.50 x 100 = $150. So the final answer is 150.
