I thought doubling everytime except for the number 19000 because if you do 250 × 2 = 500 so then you do 500×2=1000.
What do you need to know?
I can tell you that is 50 cents for cantaloupe at that price....
So I think he'd have to charge $1.50. He'd get what he paid for back plus a dollar. If C= one cantaloupe ....it would look something like
p > $1.50c
BECAUSE 1.50 x 14 = 21 minus the 7 he paid would leave you with 14... on dollar per cantaloupe... so the price can be anything greater than $1.50
This would be ( using the Pythagoras theorem) = sqrt (3^2 + 4^2) = sqrt 25
= 5 units (answer).
50 -> 35=change by 15
change by 5=10%
so multiply by 3
3(5)=3(10%)
15=30%
