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:
l-1/15l
l(1−0.15)
0.15l
l-15/100
l-3/20l
plz quick

L(1-0.15)

L-(15/100)L

Step-by-step explanation:

we  know that

100%-15%=85%

85%=85/100=0.85

so

The number of hours that Mateo spent at the beach last week is equal to the hours that landen spent at the beach (L) multiplied by 0.85

The linear equation that represent this situation is

0.85L  

Equivalent expressions are

1) L(1-0.15)

Because

Applying distributive property

L(1-0.15)=L-0.15L

Combine like terms

L-0.15L=0.85L

2) L-(15/100)L

because

15/100=0.15

substitute

L-(15/100)L=L-(0.15)L=0.85L

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
