Answer:225000 mice
Step-by-step explanation:
Mass of elephant=4500kg
Mass of mice=2x10^(-2)=2/100 kg
Let y be there number of mice
2/100 x y=4500
2y/100=4500
Cross multiply
2y=4500 x 100
2y=450000
Divide both sides by 2
2y/2=450000/2
y=225000
- The actual cost of the sweater is $18
The question says to evaluate the cost of four dollars less than the cost of a sweater.
To do this, what we have to do is to create a mathematical equation of it.
Less than always insinuates that we are to subtract, and as such, we are going to subtract four dollars from the cost of the sweater to get our final answer.
Four dollars less than the cost of a sweater that costs $22 is
22 - 4 = $18
