Ksivusya [100]

7.5795 ounces.
Multiply the weight of the bar by the percentage of silver of the bar. Make sure to turn the percentage into decimal.
8.15-93/100-7.5795.
Round to two decimals if necessary, (which is 7.58).

Here's a trick.

Don't solve all the equations, you're given the answer to x so just substitute.

5/2*8+7/2=3/4*8+14

23.5=20 INCORRECT

5/4*8-9=3/2*8-21

1=-9 INCORRECT

5/4*8-2=3/2*8-4 <- YOUR ANSWER

8=8 CORRECT

There is board connected to = 20 bulbs

And one can either be put ON or put OFF.
