Question

1) The Ramirez family has a new puppy! When they got it, it weighed 10 pounds. Since then it has

gained 2 pounds per week for x weeks. The puppy now weighs 16 pounds. Model this situation here.
Which equation represents this?
A 10x + 2 = 16
C 10x - 2 = 16
B 2x+10=16
D 2x-10=16

Answer 1

B (2x + 10 = 16)

Explanation:

initial weight = 10 pounds

2 pounds per week for x weeks, so

2 multiplied by the number of weeks

= 2x

It now weighs 16 pounds in total

so, 10 added to it's weight per week

= 10 + 2x

= 16

so

2x + 10 = 16

Answer 2

the third one (I don’t know if you put it as b on purpose or not that’s why I’m calling it the third one)

Explanation:

it’s says the puppy gained 2 pound for x weeks so you know that the variable (x) will be associated with the 2 and it already weighed 10 pounds so your adding from there.
