Question

Evan bought 6 batteries at $10 apiece and 6 batteries at $4 apiece. the total cost was the same as he would have spent buying 6 batteries at $14 apiece. So,(6x10)+ (6x4) = 6x 14.Which property dose the equation illustrate

Answer 1

6 * $10 + 6 * $4 = 6 * $14
It's the distributive law property - the formula is:

a * b  +  a * c = a * (b + c)

In this situation:

a = 6
b = 10
c = 4

And 6 * $10 + 6 * $4 = 6 * $14 is the same as 6 * $10 + 6 * $4 = 6 * ($10 + $4)
