Step-by-step explanation:
Let m be the price of 1 baby mice
Let p be the price of 1 baby python
Given,
as equation 1.
and
as equation 2
From here we can easily use elimination method
for solving simultaneous equations.
Use Equation 1 - equation 2 to eliminate m to find p.
Substitute p into equation 1.
therefore 1 baby mice cost $4.50 and 1 baby python costs $45.
Answer:
A. 650 + 35w > 825 + 15w
Step-by-step explanation:
Molly = $650
Molly's weekly additions = $35
Lynn=$825
Lynn's weekly additions= $15
Let the number of weeks = w
inequality to determine how many weeks, w, it will take for Molly's savings to exceed Lynn's savings
Molly's savings
$650+ $35w
Lynn's savings
$825 + 15w
The inequality is
650 + 35w > 825 + 15w
The inequality above will show the number of weeks it will take for Molly's savings to be greater than Lynn's savings
The set builder notation is {-8,-3,4,7} and the number line would begin at -8 and continue to positive 7. It would show a closed dot on top of -8 with a line that continues to a closed dot above 7.
The union of the 2 sets means that the final notation includes all elements.
Answer: They must sell 116 more boxes to raise $270.
Solution:
For every box they sell, they get $1.35 profit.
They have sold 84 boxes already, then they have:
$1.35 * 84 = $113.40
They need $270, then they have to sell:
$270-$113.40=$156.60
For every box they sell, they get $1.35 profit, then they need to sell:
$156.60/$1.35=116 more boxes
Check:
116*$1.35=$156.60
84*$1.35=$113.40
$156.60+$113.40=$270.00
