Question

Four friends share the profit of a lawn care service equally. The friends charge $45 per lawn and spend $30 of their total
earnings on gasoline for the lawnmowers each week. Which inequality can be used to find m, the number of lawns they need
to mow next week so that each person earns at least $275?
45m-30 2275
45m-302275
45m-30 $275
45m - 30 s275

Answer 1

Answer:

45 m - 30   ≥  275 x (4)  is the required inequality.

Step-by-step explanation:

m: The number of lawns they need  to mow next week

The charge per mowing of lawn = $45

The total earnings spent on gasoline each week  = $30

The earning per person is AT LEAST $275.

Now,if 1 person earns at least $275

So, the total minimum earnings of 4 people  = 4 x ($275)  = $ 1100

Also, of per mow charge  = $45

So, the charge of mowing m lawns  = m x ( Per mow charge )  

= m x ( $45) = 45 m

Now, according to question:

Total Earning - Money spent on gasoline  ≥  Total Earning $1100  

or, 45 m - 30   ≥   1100

Hence, the needed inequality is  45 m - 30   ≥   1100

or, 45 m - 30   ≥  275 x (4)
