Mr. Wang needs a total of 410 spoons for his son's birthday party. He currently has 278 spoonsIf has 12 spoons, what is the minimum number of sets he should buy?

Minimum amount of sets needed = 11 sets

Step-by-step explanation:

Total number of needed spoons = 410

Total number of available spoons = 278

Amount needed to be bought = 132 spoons

each set has 12 spoons

Therefore minimum amount of sets needed = 132/12 = 11 sets

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
