Respuesta :
15 tomatoes costs $10.
First, we need to convert this to a common factor.
The GCF of 6 and 15 is 3.
How do we go from 6 to 3?
Divide by 2.
6 = $4
Divide both by 2
3 = $2
How do we go from 3 to 15?
Multiply by 5
3 * 5 = 15
$2 * 5 = $10
$10 because if there is 15 tomatoes, there are two groups of six which equals $8. then there is 3 left, which is half of 6. so divide the price in half which would be $2. add it together: 8+2= $10
