Question

Landen spent
\[L\] hours at the beach last weekend. Matéo spent
\[15\%\] fewer hours at the beach than Landen did.
Which of the following expressions could represent how many hours Matéo spent at the beach last weekend?
Choose 2 answers:
A

\[L-\dfrac{1}{15}L\]
B
\[L(1-0.15)\]
C
\[0.15L\]
D

\[L-\dfrac{15}{100}\]
E

\[L-\dfrac{3}{20}L\]

Answer 1

Answer: B and E.

Reason: 15% of L is 0.15L = (15/100)L = (3/20)L, so Matéo spent L − 0.15L = L(1−0.15) = L − (3/20)L. The others are incorrect (A is L − (1/15)L, C is just 0.15L, D subtracts 0.15 hours not 15% of L).
