A) 6.5
B) -6.5
C) -6.5
D) 1.1
Change all into decimals
.2+.5=0.7
1-0.7=0.3
sponge cake=0.3
Answer:
I think its 6.25 (6 and 1/4) but I'm not a teacher or anything so it may be incorrect.
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.
