Answer:
The expression to calculate her pay should be 80+0.05(t-400)
That is assuming her 5% of the difference. The formula is her base pay (80) added to the 5% of the merchandise over 400.
The answer I got using the new formula, using 475 for t:
80+0.05(475-400) = Total pay
80+3.75= Total pay
$83.75 is her total pay that day.
Step-by-step explanation:
We are given equation: c=6.4w, where the cost c for w pounds of walnuts.
w represents the number of pounds of walnuts.
Number of pounds could be in decimals.
The value of w = 2.5 represents 2.5 pounds of walnuts.
On plugging w=2.5 in c=6.4w equation, we get.
c=6.4×2.5 = $16.
Therefore, for 2.5 pounds of walnuts the total cost is $16.
Hence, <u>a value of 2.5 for w make sense in this situation. It shows that cost of 2.5 pounds of walnuts is $16, where cost of each pound of walnuts is 6.4.</u>
Answer:
The annual percentage yield is of 2.78%.
Step-by-step explanation:
Annual percentage yield of an account:
The annual percentage yield of an account compounded n times during the year with a decimal interest rate of r is given by:
![Y = (1+\frac{r}{n})^n - 1](https://tex.z-dn.net/?f=Y%20%3D%20%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5En%20-%201)
Pays 2.75% compounded quarterly
This means that
. So
![Y = (1+\frac{r}{n})^n - 1](https://tex.z-dn.net/?f=Y%20%3D%20%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5En%20-%201)
![Y = (1+\frac{0.0275}{4})^4 - 1](https://tex.z-dn.net/?f=Y%20%3D%20%281%2B%5Cfrac%7B0.0275%7D%7B4%7D%29%5E4%20-%201)
![Y = 0.0278](https://tex.z-dn.net/?f=Y%20%3D%200.0278)
0.0278 = 2.78%
The annual percentage yield is of 2.78%.
