Vera_Pavlovna [14]

Answer:

$36.25

Step-by-step explanation:

To enter the park, Amanda pays 25 dollars.

+$25

It costs 1.25 for every ride that Amanda goes on.

Since we don't know the number of rides Amanda goes on, we will add a variable to represent the number of rides.

1.25x

Then, the passage says that Amanda goes on 9 rides. So, substitute 9 for x.

Equation: 25+1.25(9)

Then solve:

$36.25

Sir Ving Spoon earned $5,436 on his $7,550 certificate of deposit. If he had the CD for 12 years, what simple interest rate did
Lilit [14]

6% or 0.06 is the simple interest rate the bank pays him.

<u>Step-by-step explanation:</u>

Sir Ving Spoon earned $5,436 on his $7,550 certificate of deposit.

From this given information,

It can be determined that the Principal amount is $7550 and the interest amount is $5436.

The CD is for 12 years. Therefore, the number of years is 12.

<u>To find the interest rate (r) :</u>

Using the simple interest formula,

Interest = P×r×t

where,

  • P is the principal amount = $7550
  • r is the rate of interest.
  • t is the number of years = 12

⇒ 5436 = 7550 × r × 12

⇒ 5436 = 90600 × r

⇒ r = 5436 / 90600

⇒ r = 0.06

Multiply by 100 to represent in rate %

⇒ r = 0.06 × 100

⇒ r = 6%

∴ 6% or 0.06 is the simple interest rate the bank pays him.
