Using a system of equations, it is found that:

  • 38% consumes vanilla.
  • 14% consumes strawberry.
  • 45% consumes chocolate.

In our system, we have that:

  • x is the percentage of vanilla.
  • y is the percentage of strawberry.
  • z is the percentage of chocolate.

Those 3 compromise 97% of the flavors, hence:

x + y + z = 97

Vanilla sells <u>10% more than twice strawberry</u>, hence:

x = 10 + 2y

Chocolate sells <u>7% more than vanilla</u>, hence:

z = x + 7

Since x = 10 + 2y

z = 10 + 2y + 7

z = 2y + 17

Replacing in the first equation, we can solve for y:

x + y + z = 97

10 + 2y + y + 2y + 17 = 97

5y = 70

y = \frac{70}{5}

y = 14

With y, we can solve for x and for z.

x = 10 + 2y = 10 + 2(14) = 38

y = 2y + 17 = 2(14) + 17 = 45

Hence:

  • 38% consumes vanilla.
  • 14% consumes strawberry.
  • 45% consumes chocolate.
