Question

Last Sunday, the average temperature was
\[8\%\] higher than the average temperature two Sundays ago. The average temperature two Sundays ago was
\[T\] degrees Celsius.
Which of the following expressions could represent the average temperature last Sunday?
Choose 2 answers:
A
\[1.8T\]
B
\[1.08T\]
C
\[T+0.08\]
D
\[T+8\]
E

\[\left(1+\dfrac{8}{100}\right)T\]

Answer 1

8% higher means multiply by 1 + 0.08 = 1.08. So the expressions are:

B: 1.08T
E: (1 + 8/100)T

(A) is 1.8T (80% higher), (C) adds 0.08 degrees (not 8%), and (D) adds 8 degrees (not 8%).
