First let's solve for the rate, "b", by setting up a ratio with the two points given:
16.875/7.5=(ar^3)/(ar)
2.25=r^2
r=1.5
Now we need to solve for the initial value a using either point given...
7.5=a(1.5)^1
7.5=1.5a
a=5
So now we have solved for both variables and have a complete equation:
y=5(1.5)^x
Answer:
The regular price for 1 pound of flour was $ 1.29
Step-by-step explanation:
Price Percentage
$ 16.24 90
x 100
***************************
90 * x = 16.24 * 100
90x = 1,624
x = 1,624/90
x = 18.05
Now, let's calculate the price of each bag of flour, this way:
Price of each bag = 18.05/7
Price of each bag = $ 2.58 (rounding to the next cent)
Finally, we can calculate the regular price for 1 pound of flour:
Regular price for 1 pound of flour = 2.58/2
Regular price for 1 pound of flour = $ 1.29
17/20 = 0.85
0.85 is a terminated decimal
hope this helps
Answer:
$11,004.70
Step-by-step explanation:
29742.42*.28 = 8,327.8776
29742.42*.09 = 11,004.6954
8,327.8776 + 2,676.8178 = 11,004.6954
