Answer:
Step-by-step explanation:
6/4=1.5 (price per can)
10/8=1.25 (price per can)
1.25 is cheaper than 1.5
the second one is the better buy

#1 is -32
#2 is -11
#3 is -5
#4 is 6
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
