Question

mr. bolden bought g guppies and paid with a $20 bill. what is the algebraic expression to represent how much change mr Bolden got backguppy price is $3

Answer 1

Answer:

Change = 20 - 3g

Explanation:

If g is the number of guppies that Mr. Bolden bought and $3 is the price of each guppy, we can calculate the cost of all the guppies as g times $3 or:

3g

If he paid with a $20 bill, the change that he got back is the difference between 20 and 3g, so the algebraic expression for the change is:

Change = 20 - 3g
