Answer: 3.4875

Step-by-step explanation:

Here, According to the question,

Total amount is $23.25

100\% = 23.25

⇒1\% = \frac{23.25}{100}

⇒1\%= \frac{0.95}{8}

⇒ 15\%= 15\times \frac{0.95}{8} ( By multiplying 15 on both sides)

⇒ 15\%= \frac{14.25}{8}

⇒  15\%= 3.4875

Thus, 15% of $23.25 is $3.4875

Val walks 2 3/5 miles each day. bill runs 10 miles once every 4 days. in 4 days, who covers the greater distance?
babunello [35]
So if Bill runs 10 miles in those 4 days then we need to find out Val's.

2 and 3/5. Well, we already know 2*4=8
so 0.6 (which is 3/5) multiplied by 4 is 2.4.
8+2.4=10.4

So here are the results for the distance covered in 4 days :

Val = 10.4 miles
Bill = 10 miles

Therefore, I think Val covers the most distance in 4 days.
Hope I helped :)
