Answer:
At least 7 girls: 0.5^7 OR 0.0078125
At least 8 girls: 0.5^8 OR 0.00390625
<span>100% of $X plus 100% of $Y equals $1000
4% of $X plus 6% of $Y equals $58
To solve that clear the second equation of decimals by
multiplying through by 100:
Solve that by either substitution or by elimination:
X = $100 at 4% and $900 at 6%</span>
