Answer:
A tool to measure the changes in the prices of weighted average market basket of goods and services purchased by consumers, usually households.
Inverse Property, I am pretty sure. Not sure though.
A (x,-y). When you reflect over the x-axis, the y becomes negative
A=p (1+r)^t
A future value
P present value 4.98
R rate 0.04
T time
After 3 years
A=4.98×(1+0.04)^(3)
A=5.60
7.50=4.98 (1.04)^t
Solve for t
T=log(7.50÷4.98)÷log(1.04)
T=10 years
Hope it helps:-)
