predict the percentage of high school students who​ smoke, assuming that 25 25​% of adults in the region smoke. Use 25 25​, not
Vinvika [58]
In most countries, students are not allowed to smoke, so this would be downright illegal. Also, students are educated about the detrimental effects of drugs so this would reduce it further. For the statistics, it would probably be less than 1%, under the circumstances. Please give brainliest, it would be much appreciated

Tina is saving to buy a notebook computer. She has two options. The first option is to put S200 away initially and save $10 ever
BigorU [14]
The equation for the first option is Y=10x + 200
The equation for the second option is Y=30x + 100

X = one month
To find when they would be the same about you have to set the equations equal to each other

10x + 200 = 30x + 100
-10x -100 -10x -100

100= 20x

5 = x

After five months she would save the same amount. To find how much is saved you have to plug in 5 for x in one of the equations. You can always double-check 5 by plugging it in both equations and making sure you get the same answer

Y= 10(5) + 200 = 250

Y= 30(5) + 100 = 250

She would have saved $250 after five months by using either method
