Cakes are sold in a shop for double the cost of ingredients and then £3 is added. The shopkeeper uses this formula: p=2c + 3
P is the price and c is the cost of the ingredients.
find the price of the cake is the ingredients cost:
a)£2:: p(2) = 2*2+3 = 7
-----
b)£3.50:: p(3.5) = 2*3.5+3 = 10
------------------
c)£5.25:: p(5.25) = 2*5.25+3 = 13.50
----------------
d)£4.75:: p(4.75) = 2*4.75+3 = 12.50
