Jana buys a dress for $25.98 and a blouse for $14.99. The total sales tax is $2.46.

a. What is the total cost of her purchase?

b. If Jana pays with a $50 bill, how much change should she receive?

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!

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
