Answer:
The answer is "option b"
Step-by-step explanation:
Amount = $26,900
r= 0.0818
%
t= 8 years
Payment
192.
2(8+4)÷2(8+8) = 1(4+8)×(8+8)
1×12×16=192.
Estimation for addition: 86 rounds up to 90 and 17 rounds up to 20 so:
90 + 20 = 110
Estimation for subtraction is the same thing but with subtraction
90 - 20 = 70
Now for the exact answers:
86 + 17 = 103
86 - 17 = 69
Your answers are 110, 70, 103, and 69.
