Elias had 3 time as much money as munah. Elias spent $240 and munah received $60 from her brother. In the end. Elias and munah had the same amount of money. How much did elias have at first

$450

Step-by-step explanation:

let m represent the amount of money munah has

That means elias would have 3 * m or 3m dollars.

Then, you have m + 60 = 3m - 240

solve:

So munah started with $150. Since elias has 3 times as much, they have 150 * 3 = 450

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
