You lend $240 to your friend. He pays you back $30 in interest in one year. What interest
rate did you charge your friend?

12.50%

Step-by-step explanation: Lets use an equation find the the interest rate.

30 = p x 240

30/240 = p x 240/240

0.125 = p

Multiply 0.125 by 100 to get the interest rate. 0.125 x 100 = 12.5

12.5% = p

answer: h

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
