If they are decreasing at 3% , net = 100% - 3% = 97%
Reduction rate = 97% = 0.97
After 1st year = 1200*0.97
After 2nd year = 1200*(0.97)*(0.97) = 1200*(0.97)²
After 3rd year = 1200*(0.97)*(0.97)*(0.97) = 1200*(0.97)³
After x years, = 1200(0.97)ˣ
Therefore, function f(x) = <span>1200(0.97)ˣ</span>
Answer:
paco ate 1/4 cup more than levi
Step-by-step explanation:
1/2=2/4
3/4-2/4=1/4
Answer:
B
C
Step-by-step explanation:
Convert 30% to a decimal:
30% = 0.30
Check each item by multiplying the original price by 0.30 (the 30% off sale). Subtract the product from the original price. If the sale price is the same, the pricing is correct. If they are different, the pricing is incorrect.

Answer:
Options B, C, and D.
Step-by-step explanation:
The first graph is a parabola. Since it opens downwards, it means the leading coefficient is negative.
The third graph is also a parabola. Since it opens upwards, it means it has a positive leading coefficient.
The second and fourth graphs represents a polynomial with an odd degree. Since both polynomial goes rises on the left and keeps rising on the right, their leading coefficients are positive.
The correct options are:
B, C , and D
