If you want to buy an item in a store that cost $43 and is on sale for 40% off, then how much would the item actually cost you a
expeople1 [14]

Answer:

$25.80

Step-by-step explanation:

40% = 40/ 100 = 4/10 = 0,4

There is a 40% discount, which means that the amount multiplied by more then 1 (for example 1,4) would increase the amount... That isn't right because it is a discount!

So you need to subtract the 40%, so (1 - 0.4 =) 0.6

The amount multiplied by 0.6 will be the correct amount, being $43 * 0.6 = $25.80 (rounded to the nearest cent).

The amount the item actually cost after the discount is $25.80

FastForward has net income of $19,090 and assets at the beginning of the year of $209,000. Its assets at the end of the year tot
SVETLANKA909090 [29]

Given:

Net income = $19,090

Assets at the beginning of the year = $209,000.

Assets at the end of the year total = $264,000.

To find:

The return on assets.

Solution:

Formula used:

\text{Return of assets}=\dfrac{\text{Net income}}{\text{Average of assets at the beginning and at the end}}

Using the above formula, we get

\text{Return of assets}=\dfrac{19090}{\dfrac{20900+264000}{2}}

\text{Return of assets}=\dfrac{19090}{\dfrac{473000}{2}}

\text{Return of assets}=\dfrac{19090}{236500}

\text{Return of assets}\approx 0.0807

The percentage form of 0.0807 is 8.07%.

Therefore, the return on assets is 8.07%.
