-- 3 bakers produce 15 cakes in 60 minutes.
-- Each baker produces 15/3 = 5 cakes in 60 minutes.
-- Each baker takes 60/5 = 12 minutes to produce 1 cake.
-- 6 bakers can produce 6 cakes in 12 minutes.
-- 20 cakes will take 20/6 = (3 and 1/3) as much time as 6 cakes.
-- (3 and 1/3) times 12 minutes = <em>40 minutes</em>.
================================================
An easier way to do it:
-- 3 bakers produce 15 cakes in 60 minutes.
-- 6 bakers could produce 30cakes in 60 minutes.
-- Only 20 cakes are needed. That's only (20/30) = 2/3 of 30 cakes.
-- So it will only take them 2/3 of 60 minutes = <em>40 minutes</em> to make them.

Answer:
Step-by-step explanation:
$7.45 = 100g
x = 3kg( 3 × 1000) = 3000g
∵ $7.45 = 100g
x = 3000g
(100 × x) = (7.45 × 3000)
100x = 22350
100x/100 = 22350/100
x = $223.5
