Question

What’s this answer ?

Answer 1

To solve this problem, first we should figure out how many of Jorge's classmates and relatives like salsa music.

56% of Jorge's 75 classmates like salsa music. To find out how many classmates that is, we need to multiply 56% * 75 (remember that of means multiplication in math). But, we can't really multiply a percentage, so we must convert this into a decimal. To do this, we remember that 56% = 56/100, and then we divide to get 0.56 (you can also move the decimal point two places to the left). So now we can multiply:

0.56 * 75 = 42

Similarly, 80% of Jorge's 60 relatives like salsa music. 80% = 80/100 = 0.8.

0.8 * 60 = 48

48 of Jorge's relatives like salsa music and 42 of Jorge's classmates like salsa music. To find out how many more of his relatives like salsa music, we should subtract the number of classmates from the number of relatives, as follows:

48 - 42 = 6

Therefore, the answer is A) 6.
