Answer :
Answer:
$40
Step-by-step explanation:
To find out how much it would be for 10 bikes if Sindy sold 5 bikes for $20, you can set up a proportion based on the price per bike.
1. First, calculate the price per bike for 5 bikes:
If 5 bikes are sold for $20, then the price per bike is:
[tex]\text{Price per bike} = \frac{\$20}{5 \text{ bikes}} = \$4 \text{ per bike}[/tex]
2. Next, use this price per bike to find out the cost for 10 bikes:
If 1 bike costs $4, then for 10 bikes:
[tex]\text{Cost for 10 bikes} = 10 \text{ bikes} \times \$4 \text{ per bike} \\\\ \text{Cost for 10 bikes} = 10 \times \$4 \\\\ \text{Cost for 10 bikes} = \$40[/tex]
