Question

Jenny has 10 batteries. She needs more for a school project. Batteries are sold in packages of 4.if Jenny buys 16 packages of batteries, how many batteries will Jenny now have for the school project?

Answer 1

74 batteries will be what she has total for the school project.

Answer 2

74

Explanation:

Multiply 16 (packs of batteries) by 4 (amount in each package) to get 64,

`16\\*4`

⇒ 6 * 4 = 24; 10 * 4 = 40; 24 + 40 = 64

then add 10 (batteries she had before buying more).

64 + 10 = 74.

Now Jenny has 74 batteries for her school project.
