Answer:

The original price of the calculator was $444

Step-by-step explanation:

So follow this equation

1.99x=883.56

1.99 becuase 99 percent is the .99 and since the original price with no change of all is worth 100 percent With no sales or increases, we add the 99 percent this time becuase it increased by 99%.

X is for the original price of the calculator

If you still don’t undertsand it works like this.

100% is basically 1.00 becuase you move the decimal place 2 times to the left for percentages. And if you multiply the original price by 100 percent, its basically 1x which will end up with x. Same thing. But when you increase a price, you add to the 1.00 like in this case 99% increase which is adding .99 to 1.00. If it decreases same thing except you subtract from that 1.00 But the percent. this saves a whole nother step Which makes percentage questions liek these much quicker and easier.

Alright so the eqaution is 1.99x=883.56

Solve by isolating x by dividing 1.99 on both sides

You’d get 444=x

$444 is the original price
