Current. This is because the current is dependent on the light intensity which is an independent variable. The current is also affected by the light intensity.
$0.29 * 3 = $0.87
$0.98 * 2 = $1.96
$1.39 * 1 = $1.39
0.87 + 1.96 = 2.83
2.83 + 1.39 = 4.22
10.00 - 4.22 = $5.78
she will get $5.78 back!
I think it is 16 dogs but I’m not sure
