1 dozen cost 5.98
so 1.5 dozen cost : 5.98 x 1.5 = 8.97
a coupon takes $1 off the price so
8.97-1.00 = 7.97
they cost a total of $7.97
You simply cross multiply. The correct answer is B. I know this becase I had the same exact question in my Staar review packet.

Answer: Yes it is a function</h3>
===============================================
Here are some reasons why
- We can solve x+2y = 7 for y to get y = -0.5x+3.5; this equation is in slope intercept form y = mx+b. All equations in the form y = mx+b are linear and also a function.
- For any input x, there is exactly only one y value that pairs with it.
- The vertical line test can be used to effectively verify item #2 above. The idea is that it is impossible to draw a vertical line through more than one point on the graph. So it is said to pass the vertical line test.
Answer:
not similar because the lengths aren't the same.
