9. The costs for going to a dog beach are $7 for 1 dog, and $2 for each
additional dog. Which equation shows this situation, where x is greater
than or equal 1? *

Solution:

Given that,

The costs for going to a dog beach are $7 for 1 dog, and $2 for each  additional dog

Let "x" be the number of dogs

where x is greater  than or equal 1

Cost y is $7 for the first dog and $2 for each of the other dogs

Therefore,

y = 7 + 2(x - 1)

x - 1 means the additional dogs

Therefore,

y = 7 + 2x - 2

y = 2x + 5

Thus the equation is found

the answer is b.)

< 1=< 2
