  • Total * .7 = 10,000,000 Let's manipulate this to get the total on one side of the equation by itself. To do this, you need to do the same thing to both sides. Since "Total" is being multiplied by .7 (70%), let's divide both sides by .7 (70%). Total = 10,000,000 / .7 = approx 14285714.285714(repeater). To test this, do the original equation: 14285714.285714 * .7 = 9,999,999 .9999998 Since 10,000,000 / .7 cannot be calculated exactly in decimal format, the proof work will never equal exactly 10,000,000 To recap, the formula to use is Total = Number / percent
  • multiply the total by 100/70 x * 70/100 = 10,000,000 x is the original ammount x *70 = 10,000,000*100 x * 70 = 1,000,000,000 x = 1,000,000,000/70 therefore x = 14285714.285714285714285714285714 x = 14,285,714.29 rounded to 2 decimal places
  • i believe you can use the law of sine in this too. 10,000,000/70%=x/100%
  • Wow, you guys totally caved on an obvious homework question!
