Answer: The price of each gift is $5.

Step-by-step explanation:

Since we have given that

Amount = $300

Divided into equally among 5 fourth grade teachers.

so, Amount each fourth grade teacher would be

$\dfrac{300}{5}=\$60$

Since Number of hits that need to buy = 12

Each cost the same amount.

So, Price of each gift would be

$\dfrac{60}{12}=\$5$

Hence, the price of each gift is $5.

Ainat [17]

Answer:

The value of y in the given equation is B. 30.

Step-by-step explanation:

y = 2x² - 4x x = 5

y = 2(5)² - 4(5) Plug 5 in for x

y = 2(25) - 20 Square 5 and multiply 4 by 5

y = 50 - 20 Multiply 2 by 25

y = 30
