The value of the skirt with a tax is
$35.00 + ($35.00 x 0.07) = $37.45
He has $40.00 and his change will be
$40.00 - $37.45 = $2.55
Answer:
Seth watched TV for 6 3/4 hours last week.
Step-by-step explanation:
Let x be the number of hours he watched TV last week.
(2/3)x = 4 1/2 hrs. Solve for x by mult. both sides by (3/2):
(3/2)(2/3)x = (3/2)(9/2)
Then: x = 27/4 hours, or 6 3/4 hours.
Seth watched TV for 6 3/4 hours last week.
The explicit formula of the function d(n) is 
<h3>How to determine the explicit formula?</h3>
The function is given as:
d(1) = 2.7
d(n) = d(n-1) x (6.1)
The above means that the function is an exponential function, and it has the following parameters:
First term, d(1) = 2.7
Common ratio, r = 6.1
The explicit formula of an exponential function is:
So, we have
Hence, the explicit formula of d(n) is

Answer:
Juan invested $ 11,800 in Fund A and $ 7,200 in Fund B.
Step-by-step explanation:
Given that Juan invested $ 19000 in two mutual funds, and Fund A earned 7% profit during the first year, while Fund B earned 3% interest, if he received a total of $ 1042 profit, to determine how much she had invested in each mutual fund the following calculation must be performed:
19000 x 0.07 + 0 x 0.03 = 1330
15000 x 0.07 + 4000 x 0.03 = 1170
11000 x 0.07 + 8000 x 0.03 = 1010
11500 x 0.07 + 7500 x 0.03 = 1030
11800 x 0.07 + 7200 x 0.03 = 1042
Therefore, Juan invested $ 11,800 in Fund A and $ 7,200 in Fund B.
