Using a graphing calculator, find the number of hours for which the costs are the same. Round your answer to the nearest whole hour.

Take a look at that site. It is cool and interesting!
I think this would help you.

the lines intersect at (1.8, 48.3) how would i figure out what the number of hours is when they're the same price? @3mar

Answer 7

Nice question!!!!
Can you share your works/steps, please?

Answer 8

uhm, i went to the desmos website, and i typed the 35 + 7.25 x into the first bar, and 29 + 10.5x into the second. i scrolled up to see where the lines intersected, and found the cooridnates i listed above. I'm not sure what to do from there, though.

Answer 9

35 + 7.25 x = 29 + 10.5 x
6 = 3.25 x
x = 1.84 which means after 1.84 hours costs will be equal. 35 + 7.25 . 1.84 =48.3 (price when both are equal)

if you use graph, x integer of intersection point gives the hour, y integer gives the price.
Question asks for hour (x integer), so the answer is 1.8

Answer 10

ohhh! i see! so, x is after so many hours where as y is equal to the cost?

Answer 11

oh it says round it to the nearest whole. So it's 2

Answer 12

yes
