Idk what it means.why is it not reasonable to say that 4.23 is less than 4.135
RSB [31]

it is unreasonable because 4.23 is bigger than 4.135! Look at the 10s place - 1 is smaller than 2, and everything afterwards is irrelevant. There could be as many zeros or any combination of numbers you want, but as long as that tens place is larger (2 vs 1), than it's not reasonable to say 4.2 is smaller!!

Find the amount of tax and the tax rate. Round to two decimal places
Makovka662 [10]

Answer:

The tax amount is 15.17$

The tax rate is 12.4%.

Step-by-step explanation:

First we subtract the cost from the selling price.

137.17 - 122 = 15.17

We have found the tax amount, now for the tax rate.

If tax rate is x, then

122 * x = 137.17

Divide both sides by 122 to get

x = 137.17/122 = 1.124, or .124.

Then convert into percentage by moving the decimal to the right 2 times.

.124 = 12.4%

Hope this helps you

Mr.Nelson bought a coat on sale for $27 less than third its original price . He paid $54. What was the original price?
MAVERICK [17]

Answer:

$243.

Step-by-step explanation:

We can use algebra here.

Let x = the original price.

Then  1/3 x - 27 = 54

1/3x = 54 + 27 = 81

x = 81 /  1/3

x = 81 * 3

x = $243  (answer).
