Answer:
Jana has to pay a total of $43.43 and receives a change of $6.57.
Step-by-step explanation:
Step 1: Add the cost of the dress and blouse
25.98+14.99=40.97
Step 2: Sales tax is adding to the cost of the blouse and dress.
40.97+2.46=43.43
So her total cost is 43.43 dollars
If she pays with a 50 dollar bill, you need to see how much more that is than the actual cost.
50-43.43=6.57.
She will receive 6.57 dollars for change
So Jana has to pay a total of $43.43 and receives a change of $6.57.
Hope this helps!
We know that
the formula of the <span>the sum of the arithmetic sequence is
Sum=n*(a1+an)/2
n=36
a1=3
a36=?
find a36
an=a1+(n-1)*d
for n=2 a2=9
9=3+(2-1)*d----> 9=3+d----> d=6
so
for n=36
a36=a1+(36-1)*6----> a36=3+35*6----> a36=213
</span>Sum=n*(a1+an)/2-----> 36*[3+213]/2----> 3888
the answer is
3888
a. 1.732
because if the number behind the number you are rounding is 5 or greater, you go up a number, but if it is less than 5, then you leave it the same. this applies to both problems.
