Try 2. two can be in both of those.
P(y) = 0.16*y
p(y(r)) = 0.16*(y(r))
p(y(r)) = 0.16*(2.76*r)
p(y(r)) = (0.16*2.76)*r
p(y(r)) = 0.4416*r
p(y(r)) = 0.44*r
Now plug in r = 2000 to convert to pesos
p(y(r)) = 0.44*r
p(y(2000)) = 0.44*2000
p(y(2000)) = 880
Therefore, 2000 Russian rubles = 880 Mexican pesos.
Answer:
a = 80
b = 3/4
the general equation is;
y = 80•(3/4)^x
Step-by-step explanation:
Here, we want to get the values of a and b
We are going to use the two points given
(0,80) and (1,60)
So we have this as;
for the first point;
80 = a•b^0
anything raised to power of 0 is 1
Thus;
80 = a * 1
a = 80
for the second point;
60 = 80 * b^1
60 = 80b
b = 60/80
b = 3/4
So we have the general equation as;
y = 80•(3/4)^x
The integers are 3, 5 and 7 because 3+5+7 = 15
