A movie theater decreased the size of its popcorn bags by 20%. If the new bags hold 12 cups of popcorn, how much did the original bags hold? Nasser used the equation 0.20x = 12
Abraham used the equation 0.80x = 12
Kathleen used the equation 1.20x = 12

Decide who used the correct equation and defend your reasoning.

Step-by-step explanation:

A movie theater decreased the size of its popcorn bags by 20%. If the new bags hold 12 cups of popcorn, how much did the original bags hold?

Nasser used the equation 0.20x = 12

Abraham used the equation 0.80x = 12

Kathleen used the equation 1.20x = 12

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
