Ben wants to buy some albino frogs for his aquarium. He has $20 to spend and the frogs cost $2.50 each. Write, solve, and interpret an inequality to find how many frogs he can afford.

Given:

He has $20 to spend and the frogs cost $2.50 each.

To find:

The inequality to find how many frogs he can afford.

Solution:

Let x be the number of frogs he can afford.

Cost of one frog = $2.50

Cost of x frogs = $2.50x

He has $20 to spend. It means, the total cost, i.e., $2.50x, must be less than or equal to $20.

Divide both sides by 2.50.

Therefore, the maximum number of frogs he can afford is 8.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
