Answer:

10.8 yards

Step-by-step explanation:

Since she has 19.7 yards left over, the amount she used for curtains is ...

84.5 - 19.7 = 64.8 . . . . yards

Then each of the 6 identical curtains used 1/6 of this amount, or ...

(64.8 yards)/6 = 10.8 yards

_____

You can write an equation if you like. Let c represent the yardage used for each curtain. Then the total number of yards of fabric Jennifer has is ...

6c +19.7 = 84.5

We can find the value of c by subtracting 19.7, then dividing by 6 (as above).

6c = 64.8 . . . . subtract 19.7

c = 10.8 . . . . . divide by 6

Jennifer used 10.8 yards of fabric per curtain.

Answer:

After 5 years, savings account = $241.00

After 8 years, savings account = $269.53

Step-by-step explanation:

If the savings account increases by 3.8% per year, this means it will be 103.8% of the previous year's value since 100% + 3.8% = 103.8%

103.8% in decimal form = 103.8/100 = 1.038

Therefore, the exponential function is:

$y = 200 \cdot 1.038^x$ , where $x$ is the number of years

So when $x=5$ ,

$y = 200 \cdot 1.038^5=240.99984...$

After 5 years, savings account = $241.00

After 8 years, savings account = $269.53
