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?
How much will Yoque pay in 11 months? ** In 11 months, Yoque will pay a total of $15 x 11 = $<<15*11=165>>165.
How much is the total amount? ** The amount $165 is 100% + 10% = 110% of the money she borrowed.
How much is 1% of the money she borrowed? ** So, 1% is equal to $165/110 = $<<165/110=1.50>>1.50.
How much money did Yoque borrow? ** Hence, Yoque borrowed $1.50 x 100 = $<<1.50*100=150>>150.
