Patty has $20 to spend on gifts for her friends her mother gives her 5 more dollars if each gift cost $5 how many gifts can she buy?

She can by 5 gifts because if she has $20 and her mother give her 5 more 20+5=25 so 2 each gift cause $5 so you add 5 all the time until you meet 25 or count how many 5s in 25

So if she has 20$ and her mom gives her 5 more e that would be 25$. if each gift cost 5$ then you would dived 25 by 5 witch would be 5 gifts
