Answer:
c, d and f are rational numbers
Step-by-step explanation:
2.25t+ 5= 13.5t+ 14
⇒ 5- 14= 13.5t- 2.25t
⇒ -9= 11.25t
⇒ -9/11.25= t
⇒ -0.8= t
Final answer: t= -0.8~
From the calculation below, the number of days it will take region d to catch up with region c is 8 days.
<h3>How do we calculate the number of days from the word problem?</h3>
The number of days it will take region d to catch up with region c can be calculated using the following formula:
c = d + 50y ................... (1)
c = the number of boxes sold by region c = 1,800
d = the number of boxes sold by region d = 1,400
y = number of days it will take region d to catch up = ?
Substituting the relevant values into equation (1) and solving for y, we have:
1,800 = 1,400 + 50y
1,800 - 1,400 = 50y
400 = 50y
y = 400 / 50 = 8
