The amount she gains is $1500 and the amount that she loses is $1200 so in total, she is in profit of $300.
Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
As per the given,
She bought for $800 = -$800
She sold it for $900 = -$800 + $900
Then she again bought it back for $400 = -$800 + $900 - $400
Finally she sold it for $600 = -$800 + $900 - $400 + $600
She left with = $300
Total gain = $900 + $600 = $1500
Total loose = -$800 - $400 = -$1200
Hence "She makes $1500 more than she loses ($1200), making a total profit of $300".

Answer:
60cm
Step-by-step explanation:
30 (8)+70 (4)+40 (2)=600mm
1mm=0. 1cm
600mm=0. 1 (600)cm
600mm=60cm
