Answer:6.27
Step-by-step explanation: 22.8 increased by 27.5%
27.5% × 22.8 = 6.27
27.5 ÷ 100 × 22.8 = 6.27
27.5 × 22.8 ÷ 100 = 6.27
627 ÷ 100 = 6.27
Distance ran by Rudy on Monday = 2 km
Percentage of increase in distance of running each day = 15%
Let us assume that the day on which Rudy will run 4 km = x
Then
2 + 0.15x = 4
0.15x = 2
x = 2/0.15
= 13.3
From the above deduction we can conclude that Rudy will run more than 4 km on the 14th day or on Sunday. I hope the procedure is clear enough for you to understand.
If you look closely you'll see that x can take on any real value here. On the other hand, y can equal -4 (maximum) or any real number smaller than -4.
Translate this information into interval notation.
Okay? We are going to need more information that that.
