Answer:
Guppy Gummies with Frizzles
Explanation:
We calculate cross elasticity of demand between guppy gummies and other products with the formula
XED = % change in qty demanded of A / % change in price of B
For Guppy Gummies with Frizzles
XED = 4 / -5 = -0.8
For Guppy Gummies with Cannies
XED = -6 / -5 = 1.2
A negative XED denotes complementary goods and positive denotes substitutes. Complementary goods are the ones that are marketed together as they are consumed or used together whereas substitutes are used in place of each other.
Building upon the argument, Guppy Gummies and Frizzles are to be marketed together.
Hope that helps.
