Fiona earns $15 for each lawn she mows. What is the inequality to find out how many lawns she must mow to earn at least $135.
My answer
15m <_ 135
M<_ 9
Correct.
To find the inequality, you need to express the relationship between the number of lawns Fiona mows and the amount of money she earns.
Let's assume that the number of lawns Fiona mows is represented by the variable 'm'.
Since Fiona earns $15 for each lawn she mows, the amount of money she earns can be calculated by multiplying the number of lawns (m) by 15, i.e., 15m.
To determine how many lawns she must mow to earn at least $135, you can write the inequality as follows:
15m ≥ 135
In this inequality, the '≥' symbol indicates "greater than or equal to." This means that Fiona must mow at least 9 lawns to earn $135 or more.
Therefore, the correct inequality is 15m ≥ 135, and the solution is m ≥ 9.
Your answer is almost correct, but there is a small mistake in your inequality. The correct inequality to find out how many lawns Fiona must mow to earn at least $135 is:
15m ≥ 135
In this inequality, "m" represents the number of lawns Fiona must mow, and the sign "≥" indicates "greater than or equal to." Therefore, Fiona must mow at least 9 lawns (m ≥ 9) in order to earn at least $135.
