Jeff buys a jelly cake for $25. The store increases its purchase price by 200%. What is the new price for the jelly cake
you would take 200% and times it by $25 and your answer would be 50
x/25=200/100
solve the porportion to find hat x=$50, this value is the increase in cost whichneeds to be added to the original cost of $25.00
So the new price of the jelly cake is $25+$50=$75.00
