Answer:
She sent 120 emails this month.
Step-by-step explanation:
Multiply 200 by .60 (60 percent) and it will give you 120.
I used 60 instead of 40 because the problem said 40 percent less, NOT 40 percent of 200.
U have to add 60+10 then 60-10=50+20=70 and that is the answer that u u get addition subtraction those are the only to that u use.
