Daniel pays $496 in advance on his account at the athletic club. Each time he uses the club, $12 is deducted from the account. W
rewona [7]

Answer:

b = 496 - 12v

The balance is $256

Step-by-step explanation:

Given

Payment = \$496

Deduction = \$12

Required

Determine the balance after 20 visits

Represent the balance with b

Represent the visitation with v

The relationship between the given parameters is:

Payment = Deduction * Visitation + Balance

This gives:

496 = 12 * v +  b

496 = 12v +  b

Make b the subject

b = 496 - 12v

To get the actual balance after 20 visitation;

Substitute 20 for v

b = 496 - 12 * 20

b = 496 - 240

b = 256

Hence:

<em>The balance is $256</em>

Which ratio represents 36%? <br> A. 3/8 <br> B. 9/25<br> C. 7/20<br> D. 11/30
Sladkaya [172]

Answer:  B. 9/25

Work Shown:

x% = x/100

36% = 36/100

36% = (9*4)/(25*4)

36% = 9/25

Using your calculator, you should find that 9/25 = 0.36 which converts to 36%, so that helps confirm the answer.
