Which of the following is the solution to the equation 3 over 4y = 24?
Sophie [7]
3/4 y= 24

Multiply both sides of the equation by 4/3 (the reciprocal of 3/4) to be left with y.

4/3 × 3/4y = 24 × 4/3

y = 24 × 4/3

y = 32

Hope this helps!

Bezzdna [24]

Hi there!

So here's the important information we know:

He makes 15% comission on everything he sells

He sells a laptop for $293


To find out how much money Daniel makes in comission for the laptop, you need to calculate 15% of $293, which is the same thing as multiplying 15% by $293 :

15% × 293 = $

0.15 × 293 = $

43,95 = $


So your answer is: If Daniel sells a laptop for $293, he makes a comission of $43,95.


There you go! I really hope this helped, if there's anything just let me know! :)
