Question

2) A notebook cost 1.15 and a pencil cost .34. If every child must have 1 notebook and 2 pencils, how many children can be provided with supplies with $20? Pls help urgently​

Answer 1

Answer: 10 children

Step-by-step explanation:

Given:

1. Notebook cost: 1.15$
2. Pencil cost: 0.34¢
3. Every child must have 1 notebook and 2 pencils
4. 20$ given

First, let's find the cost "per child"

Notebook: 1 × 1.15

+

Pencils: 2 × 0.34

Equation for cost per child:

1(1.15) + 2(0.34)

Solve:

1.15 + 0.68

= 1.83$

We have $20. So, to find how many children can be provided with supplies, we divide 20 by 1.83 (which is the cost per child)

20 ÷ 1.83 = 10.928

(Gives us a terminating decimal)

Since we can't just give a child .928 of a set of supplies, we round down to 10.

Therefore,

10 children can be provided with supplies with $20.
