For every quarter he spends, Reggie receives 50 food pebbles to feed the fish. Reggie has thrown 350 food pebbles into the fish
deff fn [24]

Answer:

7 quarters are spent for throwing 350 food pebbles in pond.

Step-by-step explanation:

Given:

Reggie receives 50 food pebbles for every quarter he spends.

Number of food pebbles he has = 350

Let the number of quarters spent for 350 pebbles be 'x'.

Now, using proportion and cross multiplication method, we can find 'x'.

<u><em>1 quarter is equivalent to 50 pebbles thrown in pond.</em></u>

<u><em>So, 'x' quarters is equivalent to 350 pebbles thrown in pond.</em></u>

\frac{1}{50}=\frac{x}{350}\\\\Cross\ multiplying\\\\50x=350\\\\x=\frac{350}{50}\\\\x=7

So, 7 quarters are spent for throwing 350 food pebbles in pond.

Sergeeva-Olga [200]

Answer:

Bank A

Step-by-step explanation:

We find the Simple Interest for each Bank

Bank A

A savings account at bank A earns 5%

simple interest.

Where

P = $5,000.00

R = 5%

T = 2 years

Compound quarterly = 4

First, convert R percent to r a decimal

r = R/100

r = 5%/100

r = 0.05 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 5,000.00(1 + 0.0125/4)(4)(2)

A = $ 5,522.43

A = P + I where

P (principal) = $ 5,000.00

I (interest) = $ 522.43

For Bank B

P = $5,000.00

R = 4%

T = 2 years

Compound quarterly = 4

First, convert R percent to r a decimal

r = R/100

r = 4%/100

r = 0.04 per year,

Then, solve our equation for A

A = P(1 + r/n)nt

A = 5,000.00(1 + 0.01/4)(4)(2)

A = $ 5,414.28

A = $ 5,414.28

A = P + I where

P (principal) = $ 5,000.00

I (interest) = $ 414.28

Therefore, the bank that would give Gabriel more interest is Bank A
