Easy for a calculator. If you're not using a calculator, it's much more tedious!
There is an inverse sine key on your calculator, but you may have to press a key (likely labeled 2nd or INV) first. The attached image shows a TI-83 display. To get the inverse sine, I first pressed the yellow 2nd key, then the sin key.
Check MODE first to make sure you're measuring angles in degrees (if that's what you want!). Some calculators display angle mode with a small letter at the top of the display, D, R, or G usually.
The left side of the equation produces just x.
Given:
A video game customers to rent games for $4.75 each.
Customers can also buy a membership for $54 annually, and video games would only cost $2.50 each.
To find:
The number of video games a customer would have to rent in a year in order for the two options to be equal.
Solution:
Let x be the number of video games.
A video game customers to rent games for $4.75 each. So, the total cost is
Customers can also buy a membership for $54 annually, and video games would only cost $2.50 each. So, the total cost is
Now, , if the rent in a year for the two options to be equal.
Divide both sides by 2.25.
Therefore, the rent in two options are equal for 24 video games.
