I WILL GIVE 13 POINTS IF YOU SHOW YOUR WORK WITH THE ANSWER A clothing store purchased jeans from the manufacturer at a cost of
olasank [31]
First you need to find out how much Molly paid. So, $24 times 0.25 equals $6 off so $24 minus $6 equals $18. Molly paid $18 for the jeans. Then to find the percentage of increase you would find the difference between how much the store bought the jeans minus how much they sold them for which is $18-$6=$12 then u would do $12 divided by $6 which is 2 and then multiply by 100 to get 200%. So the store earned a 200% increase on the jeans they sold to Molly.

One hour on earth is four hours on planet S.
Andreas93 [3]

Answer:

The answer is 60 hours.

Step-by-step explanation:

We could use proportions to solve.

\frac{1 \: hour \: on \: earth}{4hours \: on \: planet \: s}  =  \frac{x}{240hours \:  on \: planet  \: s}

4 \times x = 4x \\ 1 \times 240 = 240

\frac{4x}{4}  =  \frac{240}{4}  \\ x = 60
