Let’s check out your problem:

Melina and Quinn use the same treadmill. Melina takes 1.5 -mile walks on the treadmill, while Quinn takes 6.5 -mile runs. If the treadmill logged over 100 miles in one month, which of the following inequalities represents the situation if 
m is the number of times Melina used the treadmill and 
q is the number of times Quinn used the treadmill that month?
Choose 1 answer:
(A) 
1.5 m+6.5 q > 100
(B) 
6.5 m+1.5 q > 100
(C)

Q. Melina and Quinn use the same treadmill. Melina takes 11.55 -mile walks on the treadmill, while Quinn takes 66.55 -mile runs. If the treadmill logged over 100100 miles in one month, which of the following inequalities represents the situation if m m is the number of times Melina used the treadmill and q q is the number of times Quinn used the treadmill that month?\newlineChoose 11 answer:\newline(A) 1.5m+6.5q>100 1.5 m+6.5 q>100 \newline(B) 6.5m+1.5q>100 6.5 m+1.5 q>100 \newline(C) 8mq>100 8 m q>100 \newline(D) 8(m+q)>100 8(m+q)>100
  1. Determine Inequality: We need to determine the inequality that represents the total distance covered by Melina and Quinn on the treadmill. Melina walks 1.51.5 miles each time she uses the treadmill, and Quinn runs 6.56.5 miles each time he uses it. We are given that the total distance logged on the treadmill is over 100100 miles in one month. We will use the variables mm for the number of times Melina used the treadmill and qq for the number of times Quinn used the treadmill.
  2. Find Melina's Distance: To find the total distance Melina walked, we multiply the number of times she used the treadmill mm by the distance she walks each time 1.51.5 miles. This gives us the expression 1.5m1.5m for Melina's total distance.
  3. Find Quinn's Distance: Similarly, to find the total distance Quinn ran, we multiply the number of times he used the treadmill qq by the distance he runs each time 6.56.5 miles). This gives us the expression 6.5q6.5q for Quinn's total distance.
  4. Calculate Total Distance: To represent the total distance logged on the treadmill by both Melina and Quinn, we add their individual distances together. This gives us the expression 1.5m+6.5q1.5m + 6.5q.
  5. Form Inequality: Since the treadmill logged over 100100 miles, the sum of Melina's and Quinn's distances must be greater than 100100. Therefore, the inequality that represents this situation is 1.5m + 6.5q > 100.
