Step-by-step explanation:

First figure out how much he spent on lunch

1/4 * 20 = 5

Then determine how much he spent on music

1/2*20 = 10

He spend 5+10 = 15

He had 20

20 -15 =5

He had 5 dollars left to save

So he saved 5 dollars

answer: howdy

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.

hope this ! : 3
