First, you would want to find the price of 1 pen, since 5 pens doesn't go into 8 pens evenly. To do this, you would have to divide 5 pens and $3 by 5, because remember, whatever you do to one side, do to the other. Anyways, 5 pens divided by 5 is 1 pen, and $3 divided by 5 is $0.60, so the price of one pen is 60 cents. To find the price of 8 pens, multiply $0.60 by 8. That gives you $4.80, so the price for 8 pens is $4.80.
Oops wrong one man I’m sorry
This is an exponential growth function.
If we look at the number that is raised to the power of x, it is greater than 1. Though there is a fraction within this equation, it is not affected by the exponential.
Hope this helps!! :)
