Step-by-step explanation:

Since <em>a</em> is the final altitude after <em>t</em> minutes, we can plug in 21,000 for <em>a</em> in the given equation.

21,000 = 3400t + 600

Solve for t.

20,400 = 3400t

t = 6 minutes

Samantha has 23 strawberries and wants to put 4 strawberries into each bowl. How many bowls can Samantha put exactly 4 strawberr
Bogdan [553]

4 cannot go into 23 equally BUT! if you do 23 divided by 4 you'll get 5.75 which rounds up to 6. So on average she'll need 6 bowls for her 23 strawberries.

Edit: It should be 5 bowls because if she wants to put an equal amount of strawberries into her bowls it should be 5.

Hope it helped. :)
