A snack bar seils scoops of strawberry, chocolate, and vanilla ice cream. On Monday, the snack bar sold
100 scoops in total of these flavors of ice.cream. The
snack bar sold 3 times as many scoops of chocolate as
it did strawberry and 2 times as many scoops of
vanilla as it did chocolate. How many scoops of
chocolate ice cream did the 'snack bar sell on
Monday?

600/11

Step-by-step explanation:

scoops of

strawberry= x

chocolate= y

vanilla ice cream= z

X+y+z= 100

The snack bar sold 3 times as many scoops of chocolate as it did strawberry

3x= y

X= y/3

and 2 times as many scoops of

vanilla as it did chocolate

2z= y

Z= y/2

X+y+z= 100

Y/3 + y +y/2 = 100

2y + 6y + 3y = 600

11y= 600

Y= 600/11

Step-by-step explanation:

The populations in millions of the different countries can be represented by the equations ...

  c = 5.2(1.025^t)

  d = 5.2(1.001^t)

We want to find d when c = 10. Solving for t when c=10, we have ...

  10 = 5.2(1.025^t)

  10/5.2 = 1.025^t

  log(10/5.2) = t×log(1.025)

  t = log(10/5.2)/log(1.025)

Then the value of d for that value of t is ...

  d = 5.2(1.001^(log(10/5.2)/log(1.025)) ≈ 5.3394789

The population of Denmark is about 5,339,479 when the population of Chad is 10 million.

If we round the number of years to 26.5 before computing the population of Denmark, we get 5,339,571 -- about 92 more people. Ordinarily, one would not round intermediate results.
