The answer is $1.85
Step-by-step explanation:
<h3>
<u>Given</u>;</h3>
- The cost of 5 chocolate bars = $5.75
- The cost of 2 chocolate bars and 3 packets of sweets = $7.85
<h3>
<u>To </u><u>Find</u>;</h3>
- 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
