Answer:
we conclude that an inequality 'c ≥ 5' denotes this situation.
Step-by-step explanation:
Given
- A car dealer ship sells at least 5 minivans
When we talk about 'at least', it means we are talking about '≥' in terms of representing the 'at least' in inequality symbol.
For instance,
'm≥n' means 'm' is greater than or equal to 'n'.
It means 'm' is at least equal to 'n'.
Coming back to the question,
- Let 'c' represent the number of minivans sold each week.
As the car dealer ship sells at least 5 minivans. so the
inequality will be: c ≥ 5
Thus, we conclude that an inequality 'c ≥ 5' denotes this situation.
The system of equations representing these costs are; y = 7.5x and y = 5.5x + 10
<h3>How to find the equation of a line?</h3>
The slope of the first line is;
m = (y2 - y1)/(x2 - x1)
m = (32 - 10)/(4 - 0)
m = 5.5
Now, the first coordinate has a y-intercept of 10. Thus, the equation here for the cost is; y = mx + c = 5.5x + 10
The slope of the second line is;
m = (y2 - y1)/(x2 - x1)
m = (15 - 0)/(2 - 0)
m = 7.5
Now, the first coordinate has a y-intercept of 0. Thus, the equation here for the cost is; y = mx + c = 7.5x + 0 = 7.5x
Thus, the system of equations representing these costs are;
y = 7.5x and y = 5.5x + 10

X = large boxes and y = small boxes
x + y = 70.....x = 70 - y
60x + 65y = 4300
60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs
x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs
