Question

To adopt a dog from an animal shelter, you must pay $90 for vaccinations, $75 to spay or neuter the dog, and $40 for a wellness exam by a veterinarian.

a. Write an expression in simplest form that represents the amount (in dollars) it costs to adopt x
dogs.
An expression is () dollars.

Answer 1

you must pay this for each dog, then you're multiplying each dollar amount by x. Ex: if you buy 1 dog, you pay 80 + 65 + 50. If you adopt 2, you pay (80 * 2) + (65 * 2) + (50 * 2).

So the answer is 80x + 65x + 50x...

BUT! You can simplify by adding the coefficients: 80 + 65 + 50 = 195.

Your answer is 195x.

Hope this helps! You can try with different values to make sure you understand it.
