A store sells mugs. Each mug costs the same amount. During a sale, the store reduces the price of each mug by $1.75. Wen spends
Ostrovityanka [42]

Answer:

  • $7.39

Step-by-step explanation:

Let the initial price be x

<u>Then the reduced price is </u>

  • x - 1.75

<u>If 5 mugs cost $28.20, we have equation:</u>

  • (x - 1.75)*5 = 28.20
  • x - 1.75 = 28.20/5
  • x - 1.75 = 5.64
  • x = 1.75 + 5.64
  • x = 7.39

Initial price for 1 mug was $7.39

Samantha is studying the population growth of an endangered birth. The growth can be modeled by the equation B(t) 100 + 3/5t^5 ,
solong [7]

The value of the population of the growth of an endangered birth after 5 years is 1975

<h3>How to determine the population after 5 years?</h3>

The population function is given as:

B(t) = 100 + 3/5t^5

At 5 years, the value of t is 5

So, we have

t = 5

Next, we substitute 5 for t in the equation B(t) = 100 + 3/5t^5

This gives

B(5) = 100 + 3/5 * 5^5

Evaluate the exponent

B(5) = 100 + 3/5 * 3125

Evaluate the product

B(5) = 100 + 1875

Evaluate the sum

B(5) = 1975

Hence, the value of the population of the growth of an endangered birth after 5 years is 1975
