30÷5=6
4×5=20
for every 30 green lights there are 20 white lights
1) is the correct answer because you just have to arrange them by degree
X=12x+55
y=-3x-14
simplfy to the right side
KP - break this one down to three parts: Total cost of shirts, total cost of shirts and the skirt, and then including tax.
3 T-shirts for $25.67 each would be 3 * 25.67 = 77.01
Shirts and skirt would be 77.01 + 23.55 = 100.56
Tax can be found quite a few different ways, the easiest of which would be multiplication.
8% = .08
100.56 (total cost of clothes) * .08 (tax) = $8.05
Now just add tax and total cost of the clothes. Because of rounding, our answer might be slightly different but that's okay because it's multiple choice and only 1 answer makes sense!
