Step 1: Given

Elena purchases bottle of 250 tablets and takes 2 per day.

Step 2: Solution

a) Formula for number of tablets left of after she takes it for x number of days, she uses 2 tablets per day, so tablets used in x days$=2x$

Tablets left$=250-2x$

b) Lets find the tablet left after 30 days using above formula we get,

Tablets left$=250-2x$

$=250-2\left(30\right)$

$=250-60$

$=190$ tablets

Thus 190 tablets left after 30 days.

c) For her to run out of tablet ,tablet left$=0$

lets calculate number of days(x) using above formula.

Tablets left$=250-2x$

$0=250-2x$

$2x=250$

$x=125$ days

Thus it will take 125 days for her to run out of tablet.

Step 3: Conclusion

a) Tablets left$=250-2x$

b) 190 tablets are left after 30 days.

c) It will take 125 days for her to run out of tablet.

Elena purchases bottle of 250 tablets and takes 2 per day.

Step 2: Solution

a) Formula for number of tablets left of after she takes it for x number of days, she uses 2 tablets per day, so tablets used in x days

Tablets left

b) Lets find the tablet left after 30 days using above formula we get,

Tablets left

Thus 190 tablets left after 30 days.

c) For her to run out of tablet ,tablet left

lets calculate number of days(x) using above formula.

Tablets left

Thus it will take 125 days for her to run out of tablet.

Step 3: Conclusion

a) Tablets left

b) 190 tablets are left after 30 days.

c) It will take 125 days for her to run out of tablet.

Step 1

a. She takes two tablets out each day. Let x denote the days since she started consuming the tablets. The number of tablets T left in the bottle after x days is then$T=250-2x$

Step 2

b. We substitute in the above formula$x\Rightarrow 30$ to get

$T=250-2\left(30\right)=250-60=190$ tablets

Step 3

c. We solve for x by setting$T\Rightarrow 0$ .

$0=250-2x$ rearrange the terms/isolate x

$2x=250$ divide by 2

$x=125$

So it'll take 125 days for her to run out of tablets.

a) Formula for number of tablets left of after she takes it for x number of days, she uses 2 tablets per day, so tablets used in x days =2x

Tablets left =250-2x

b) We substitute in the formula x

=250-2x

=250-2(30)

=250-60

=190 tablets

c) For her to run out of tablet ,tablet left =0

=250-2x

0=250-2x

2x=250

x=125 days
