Answer:
$6.47 for each shirt
Step-by-step explanation:
If s is the cost of a shirt, then the cost of 5 shirts is ...
5s = $32.35
s = $32.35/5 = $6.47 . . . . . divide both sides of the equation by 5
The cost of each shirt was $6.47.

The equation formalizes the math for you, perhaps helping you see that division by 5 is required.
To find cost per shirt, divide cost by shirts. "Per" can often be thought of as meaning "divided by."
The first equation has to be the sum of hotdogs and hamburgers. Since a total of 300 <span>hamburgers and hotdogs was sold, the first equation is:
h+d=300
Now, the second equation is about the money. They say that EACH hamburger cost $2 and each hotdog cost $1. And, the total amount of money made was $420. So the second equation is:
2h+d=420
SO, overall, the system of equations is this:
h+d=300
2h+d=420

First, we determine how many months are there in two years. We know that each year has 12 months. With these, there are 24 months in 2 years. Solving for the number of crickets in two months,
f(x) = 160 x (2^24/2)
= 655,360
Therefore, after 2 years there are 655,360 crickets.
