Question

Mitch is replacing all the light bulbs in his home with energy efficient LED light bulbs. How many packages of 4 will he need to buy to replace 86 light bulbs in his home? A) 20 C) 22 B) 21 D) 23

Answer 1

Mitch will need to buy 22 packs.

Explanation:

My favorite thing to do in these kinds of equations is to multiply 4 times the choices im given. In this case multiplying 4 and 22 gives us 88. Even though this is a bit too much, buying 20 packs will only give us 80, buying 21 will give us 84, and buying 23 will give us 92 which is far too many.

Answer 2

Answer: 22 packages so B
