Question

5 chocolate bars cost $5.75

2 chocolate bars and 3 packets of sweets cost $7.85 work out the cost of one packet of sweets

Answer 1

The answer is $1.85

Explanation:

Given;

• The cost of 5 chocolate bars = $5.75
• The cost of 2 chocolate bars and 3 packets of sweets = $7.85

To Find;

• The cost of one packet of sweets.

Now, we know that the cost of 5 chocolate bars are $5.75.

For 1 chocolate bar

5.75 ÷ 5 = $1.15

Here, we get the price of 1 chocolate bar

So, the cost of 2 chocolate bars and 3 packets of sweets are $7.85.

2 × chocolate bar = 2 × (1.15) = $2.3

Now, we want to find only the cost of one packet of sweets.

So,

7.85 – 2.3 = $5.55

3 packets of sweets cost $5.55

For 1 packets of sweets

5.55 ÷ 3 = $1.85

Thus, The cost of one packet of sweets = $1.85
