X = 250 mg tabs
y = 500 mg tabs
2200x + 1800y = 39200....multiply by -1
2200x + 2200y = 44000
--------------------------------
-2200x - 1800y = - 39200 (result of multiplying by -1)
2200x + 2200y = 44000
--------------------------------add
400y = 4800
y = 4800/400
y = 12...... the 500 mg tabs (y) costs $ 12 per bottle
2200x + 2200y = 44000
2200x + 2200(12) = 44000
2200x + 26400 = 44000
2200x = 44000 - 26400
2200x = 17600
x = 17600/2200
x = 8 <== the 250 mg tabs (x) costs $ 8 per bottle
To convert from a fraction to a percent,
You just need to divide the fractions then multiply the product by 100.
Examples:
1. What is 3/4 in percent?
a. 3/4 = 0.75 x 100 = 75%
b. 45/98 = 0.46 x 100 = 46&
c. 60/100 = 0.6 x 100 = 60%
d. 1/5 = 0.2 x 100 = 20&
e. 6/99 = 0.06 x 100 = 6%
To make 5.6e12 standard you simply move the decimal place right 12 times
5,600,000,000,000
5 Trillion 600 billion
