If a jigsaw puzzle is priced 17.00 but cost 17.68 at the register what is sales tax rate

Answers

Answer:4%

Step-by-step explanation:

From the question, we are informed that a jigsaw puzzle is priced 17.00 but cost 17.68 at the register. This means that the sales tax is (17.68 - 17.00) = 0.68.

Therefore, the sales tax rate will be calculated as:

= (0.68 / 17.00) × 100

= 4%

The sales tax rate is 4%

darcy likes to eat peanut butter and raisins on apple slices. on each apple slice she puts 1/16 cup of peanut butter and 8 raisine.Darcy has 2/5 cup of peanut butter and 80 raisins . She eats a whole number of apple slice until the peanut butter is all gone . what fraction of the 80 raisins did she eat ?

Answers

The answer is 7/10.

For one apple slice, Darcy needs 1/16 cup of peanut butter and 8 raisins. She has 2/5 cup of peanut butter. To compare how many butter she has and she needs we will divide 2/5 with 1/1

This means that Darcy needs 5/80 cup of peanut butter and 8 raisins.
If she has 32/80 cup of peanut butter, she will have it only fo 6 or 7 apple slices (32/80 ÷ 5/80 = 6.4) depending how it is rounded. If she prepares 6 apple slices, she will still have a little of peanut butter left (0.4 = 2/5 of cup). So, she will prepare 7 apple slices so the butter will be all gone.

For 7 apple slices, she needs 56 raisins (7 × 8 raisins).
That is 56 raisins out of 80 raisins, so fraction of the 80 raisins did she eat is:
$(56)/(80) = (7)/(10)$

A sneaker store salesman had $4,125 in total monthly sales last month. he made $165 in commission from those sales. what is the salesman's commission as a percent of his total monthly sales?

Answers

He made $(165)/(4125)$ as a commission. To turn that into a percentage, you need to make the bottom become 100. Multiply the top and bottom by $(100)/(4125)$ to get the proper fraction. The fraction now is $((16500)/(4125))/(100)$ This simplifies to $(4)/(100)$ . Now all you need to do is take the top of that fraction to get the percentage, which is 4%.

To find the number of miles in 100 kilometers, _____.a.divide 100 by 1.609
b.multiply 100 by 1.609
c.multiply 100 by 3.281
d.divide 100 by 3.281

Answers

Answer:

a.divide 100 by 1.609

Step-by-step explanation:

We know the relation between miles and kilometers

1 mile = 1.609 km

Now, we have to convert 100 km to miles.

Let x miles in 100 kilometers.

Hence, we have

$(1)/(1.609)=(x)/(100)\n\nx=(100)/(1.609)$

Therefore, we can see that we have divided 100 by 1.609 in order to find the number of miles in 100 km.

Therefore, a is the correct option.

multiply 100 by 1.609
