Question

Mu is walking laps to raise money for charity. For each lap she walks, her sponsors will donate $7. Mu has walked l laps and raised a total of $150

Write an equation to describe this situation.

Answer 1

7l=$150
l= 21.82 so mu would have to walk 22 laps to make $154 ; 21 laps would only make $147 . And there is no such thing as 21.82 laps .
However if you only needed the equation it is 7l=150

Answer 2

7
`l`=150

Explanation:

Each lap is worth $7, so if Mu walked
`l` laps and the total is $150, then the equation would be

`l`=150
