Answer:

There were 9 cats at the shelter on Wednesday.

Explanation:

Per day cost to care for each cat = $2.00

Per day cost to care for each dog = $6.50

Total Cost on Wednesday = $44.00

Suppose

Number of cats = C

Number of dogs = D

According to given condition

C + D = 13 (Equation 1)

( each cat's per day cost x Number of cats ) + ( each dog's per day cost x Number of dogs ) = Total coat

2C + 6.5D = 44 (Equation 2)

Multiply (Equation 1) by 2 and we get

2C + 2D = 26 (Equation 3)

Subtract (Equation 3) from (Equation 2)

2C + 6.5D - 2C - 2D  = 44 -26

4.5D = 18

D = 18/4.5

D = 4

by placing value of D in (Equation 1)

C + 4 = 13

C = 13-4

C = 9

Answer:

Hiệu trưởng, P = $71428.57

Explanation:

Cho các dữ liệu sau đây;

Thời gian = 7

năm Lãi suất = 10%

Lãi suất đơn giản = $50,000

đô la Để tìm số tiền gốc;

Về mặt toán học, lãi đơn giản được tính bằng công thức này;

S.I = \frac {PRT}{100}

Ở đâu;

  • S.I là lãi suất đơn giản.
  • P là hiệu trưởng.
  • R là lãi suất.
  • T là thời gian.

Thay vào công thức, ta có;

50000 = \frac {P*10*7}{100}

50000 = \frac {70P}{100}

Cross-multiplying, we have;

50000 * 100 = 70P

5000000 = 70P

P = \frac {5000000}{70}

<em>Hiệu trưởng, P = $71428.57</em>
