I would feel better if you'd explain how you "know" that a "same-day" ticket is $15.
"<span>The combined cost of one advance ticket and one same-day ticket is $35." This would imply that the cost of one advance ticket is $(35-15), or $10.
Check by substitution to determine whether $15 and $10 are correct. If not, please show your work, so that someone else or I could step back in and help.

Answer: it contains 200 grams of zinc.
Step-by-step explanation:
Ratio of zinc to copper is 4 to 15 = 4;15
Total ratio = 4+15= 19
We first find amount of both zinc and copper( the whole chemical) which is equal to
ratio of copper / total ratio x (the entire chemical--total grams of zinc and copper) =amount of copper
15/19 x X = 750
X= 750 X 19 / 15= 950 grams
To find amount of zinc in the chemical = ratio of zinc / total ratio x total amount of chemical
=4/19 x 950
=200 grams
42.66 / 22 = 1.939, So if you are estimating than anything that is 5 or over is estimated to the top, and anything 4 or less is estimated to the bottom. So in this case 1.939 is estimated to 1.94
The product of 800x500 is 400,000
what i normally do is 8x5, which is 40.
after i get the product, i add all of the zeros.
so, the product of your question is 400,000
