you download a video game on your computer. you have a 60-minute free trial of the game. it takes 5 1/6 minutes to set up the ga

iren2701 [21]

Answer:

B. $5\frac{1}{6}+(7\frac{1}{3})l \leq 60$

Step-by-step explanation:

Given,

The time for set up the game = $5\frac{1}{6}$ minutes,

Also, the time for each level of game is $7\frac{1}{3}$ minutes,

If there are l levels of games,

Then the time taken in all levels of game = $(7\frac{1}{3})l$

Hence, the total time ( in minutes ) = Set up time + time in all level

= $5\frac{1}{6}+(7\frac{1}{3})l$

We have 60-minute of free trial of the game,

So, the total time taken can not be exceed to 60 minutes,

$\implies 5\frac{1}{6}+(7\frac{1}{3})l \leq 60$

Which is the required inequality.

Option 'B' is correct.

the selling price for a refrigerator is 584 if the mark up is 25% of the dealers cost, what is the dealers cost of the refrigera

tia_tia [17]

25% of 584 is 146. If you meant to say "25% off of the dealer's cost", the answer would be $438, since you're finding what 25% of the original price is (146) and subtracting it from the original price. The equation would be 584 - 146 = 438. I hope this helped <3
