Tamaras dosage of medication has recently decreased 20 milligrams per day. what is the total decrease in tamaras medication at the end of the week

I think the answers would be 120 milligrams for the whole week.

So, if she had started on the first day of the week, the first week should not be included on the count. Next, there are 7 days in one week. Since the first day is not included, you will start counting the number of days from the 2nd day until the 7th day.

We let x be the total dosage decreased in the span of one week

X=( 7 days-1 day) * 20 milligrams per day

X=6*20 milligrams

X=120 milligrams decreased by the end of the week.

i think the answer is strength
