Please help me out on these word problems, I'll give 10 points to the best answer!
4. For teacher appreciation week, you got your Algebra teacher 3 flowers and 5 balloons. Your friend went to the same store and got 5 flowers and 8 balloons. Your bill was $18.75 and your friend’s bill was $20.50. Which system of equations would represent the cost of flower and a balloon?
a. 3f+5b=20.50
5f+8b=18.75
b. f+b=21
8f+13b=39.25
c. 3f+5b=18.75
5f+8b=20.50
d. f+b=21.00
3f+5b=18.75
6. The perimeter of a rectangle is 120 meters. Its length is 3 times its width. Find the dimensions of the rectangle. type in the length ONLY

4 -> c
3 flowers + 5 baloons cost $18.75
5 flowers + 8 baloons cost $20.50
6. Permimeter = 2 * length * width
Width = w
Permimeter = 2 * (width + Length)
120 = 2 * w + (3 * w)
120 = 2 * 4w
120 = 8w
15 = w
Length = 3 * width
Length = 45
enable x be the style of $10 charges and y be the style of $20 charges x + y = 30 10x + 20y = 330 x = 30 - y 10(30 - y) + 20y = 330 3 hundred - 10y + 20y = 330 3 hundred + 10y = 330 10y = 30 y = 3 x + 3 = 30 x = 27 so which you have 27 $10 charges and 3 $20 charges
For the first one would it be C?
and for the next one the length would be 45 meters?
