His sister is 8 because twice his sisters age is 8+8=16 and 16+3=19
1. add 5 6 7 13 and 14
2. divide the sum by 5
3. take that number and subtract it from 5 6 7 13 and 14
4. add those numbers together
5. u got the answer =3
6c + 8a - 200 = 1000 ....or could be 6c + 8a = 1200
if no kids came...only adults..
6(0) + 8a = 1200
8a = 1200/8
a = 150 <== 150 adults would have to attend
If you would like to know how much money did they collect in total, you can calculate this using the following steps:<span>
Travis ... t = $43
Jessica ... j
Robin ... r
120% of j is t
120% * j = 43
120/100 * j = 43
j = 43 * 100 / 120
j = $35.83
r = 135% of t = 135% * 43 = 135/100 * 43
= $58.05
t + j + r = $43 + $35.83 + $58.05 = $136.88</span>
<span>The correct result would be C. $136.88.</span>
