![\frac{3 +/- \sqrt{5} }{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%20%2B%2F-%20%20%5Csqrt%7B5%7D%20%7D%7B2%7D%20)
Remember to use a = 1, b = -3 and c = 1 in the quadratic formula.
Dividing a number by 10 moves the decimal over one place to the left. Knowing this:
7 ÷ 10 = 0.7
Answer:
Part a) The expression is ![3.2445x](https://tex.z-dn.net/?f=3.2445x)
Part b) Customer cannot buy 2.5 ounces of paprika and have it shipped for less than $8.00
Step-by-step explanation:
<u><em>The complete question is</em></u>
A spice store charged 2.75 for 25 grams of paprika. It also charges 5% of the purchase price for shipping any order.
Part a) Write and simplify an expression to determine the cost of buying and shipping x ounces of paprika. Use 1 ounce = 28 grams
Part b) Can a customer buy 2.5 ounces of paprika and have it shipped for less than 8.00? Explain
step 1
Convert grams to ounces
Remember that
![1\ oz=28\ g](https://tex.z-dn.net/?f=1%5C%20oz%3D28%5C%20g)
To convert grams to ounces divide by 28
![25\ g=25/28= 0.89\ oz](https://tex.z-dn.net/?f=25%5C%20g%3D25%2F28%3D%200.89%5C%20oz)
The unit price is
![2.75/0.89=3.09\frac{\$}{oz}](https://tex.z-dn.net/?f=2.75%2F0.89%3D3.09%5Cfrac%7B%5C%24%7D%7Boz%7D)
Let
x ----> the number of ounces of paprika
y ----> the cost of buying and shipping x ounces of paprika
5%=5/100=0.05
![y=3.09x+(3.09x)0.05\\y=3.09x[1+0.05]\\y=3.2445x](https://tex.z-dn.net/?f=y%3D3.09x%2B%283.09x%290.05%5C%5Cy%3D3.09x%5B1%2B0.05%5D%5C%5Cy%3D3.2445x)
Part b) For x=2.5 oz
substitute in the equation
![y=3.2445(2.5)=\$8.11](https://tex.z-dn.net/?f=y%3D3.2445%282.5%29%3D%5C%248.11)
![\$8.11 > \$8.00](https://tex.z-dn.net/?f=%5C%248.11%20%3E%20%5C%248.00)
therefore
Customer cannot buy 2.5 ounces of paprika and have it shipped for less than $8.00
