You increase the size of a page by 50%. Then you decrease it by 50%. What is the size of the page now?

Answers


We can't tell what size the page is now, because you never told us
what size it was before all the shenanigans started.  All you gave us
was a couple of ratios.

And you didn't even tell us WHAT was increased and decreased ...
was it the length of the sides, or was it the area of the page ?
__________________________________________

If it was the length of the sides ...

Let's say the page was  8"  high and  4"  wide.

Increase lengths by  50% :     Now it's  12"  high and  6"  wide.

Decrease lengths by  50% :   Now it's  6"  high and  3"  wide.

     The sides are now  3/4  as long as they started out,
     and the area is  9/16  of what it started out.

Lana earned $49 dollars on Friday, $42 on Saturday, and $21 on Sunday selling bracelets. she sold each bracelets for the same amount. What is the most she could have charged for each bracelet?

Answers

I believe 7, but I could be wrong.

Final answer:

The most Lana could have charged for each bracelet is $49, assuming she sold one bracelet per day.

Explanation:

Lana earned money over the weekend by selling bracelets. She earned $49 on Friday, $42 on Saturday, and $21 on Sunday. To find the most she could have charged for each bracelet, we should make the assumption that she only sold one bracelet per day, as that would mean she would be earning the maximum per bracelet. Therefore, the most she could have potentially charged for each bracelet would be the highest amount she earned in a day, which was $49.

How to solve 3n+9=7n-15

Answers

Simplifying3n + 9 = 7n + -15
9 + 3n = 7n + -15
9 + 3n = -15 + 7n
9 + 3n = -15 + 7n

9 + 3n + -7n = -15 + 7n + -7n
3n + -7n = -4n9 + -4n = -15 + 7n + -7n
7n + -7n = 09 + -4n = -15 + 09 + -4n = -15
9 + -9 + -4n = -15 + -9
9 + -9 = 00 + -4n = -15 + -9-4n = -15 + -9
-15 + -9 = -24-4n = -24
