All you have to do is divide 321 by 3 to get $107.00 each night
The two problems are almost identical: you have to set up a system, and then solve it.
In the first case, let and be, respectively, the number of girls and boys.
We know that (the number of girls in the Spanish Club is four more than twice the number of boys). Also, we know that (there are 61 students in total).
So, we have the system
We can use the first equation to substitute in the second
And then solve for :
For the second problem, let and be the number of pins knocked down by, respectively, Carrie and John. Just like before, we have the system
And you can solve it in the very same way we solved the previous one.
The length of one side is 8 centimeters.
Extra information:
When the area is square, it means that all sides are the same size. When the area of the square is 64 centimeters, it means that the length of one side is the opposite of square: square root. Therefore if you take the square root of 64, you end up with 8. You can check this, by "imagining" the length of the sides (8 centimeters) and calculate the area. This is done by multiplying the length by width. The length and width are both 8, so the area will be 64. Therefore the length is correct!
