Your city is having a sneaker convention! A pair of Ground Morgans is 20% less expensive than a pair of Elite Butterflies, Elite
Amanda [17]

Answer:

Ground Morgans are 52% the price of Floating Jumps.

Step-by-step explanation:

A pair of Ground Morgans GM is 20% less expensive than a pair of Elite Butterflies EB, this means

GM= 0.8 EB <em>(GM is 80% the price of EB's)</em>

Elite Butterflies EB are 30% more expensive than Cloud Trainers CT's, this means

EB =1.3 CT <em>(EM's is 130% the price of CT's)</em>

Cloud Trainers CT are 50% less expensive than Floating Jumps FJ, this means

CT=0.5FJ <em>(CT is 50% the price of FJ)</em>

Now, if we want the price of Ground Morgans in terms of Floating Jumps, then, since EB = 1.3 CT,

GM=0.8 (1.3CT)

and since CT = 0.5F, we have

GM = 0.8(1.3(0.5FJ)).

Simplifying we get

\boxed{GM =0.52FJ}

Ground Morgans are 52% the price of Floating Jumps.
