Answer:
Step-by-step explanation:
The two ringtones will cost her a total of 
and is a fixed amount. The relationship between the cost and number of songs only is 
and therefore the answer is 
. You can also directly find the answer by finding the y-intercept (in this case 
), as no other answer choices include the term , so A must be the correct answer.

Let student tickets are x and adult tickets are y
x + y = 516.........x = 516 - y .........(substitute in 2)
3x + 5y = 2046 ......(2)
3(516-y) + 5y = 2046
1548 - 3y + 5y = 2046
2y = 498
y = 249
x = 516 - y = 516 - 249 = 267
so the correct answer is b
Area of a rectangle is given by the formula length x width
length x width = 60ft^2
if the length is an irrational number then most likely the width can be one too
for example
length = 60^1/2
then width must be 60^1/2
since 60^1/2 * 60^1/2 = 60ft^2
