(X + .3X) / (X - 0.5X) = 1.3X/0.5X
1.3/0.5 = 2.6
2.6 x 100 = 260 %
200+12m= 644
subtract 200 from both sides
12m= 444
divide both sides by 12
m= 37
he sold 37 albums
--Percent means out of 100, so 20% = 20/100
The prob in other words is asking
-- $60 is 20% of what number?
'$60' -- ---> 60
'is' -- ---> =
20% -- ---> 20/100
'of' -- ---> * (multiply)
'what number' ---> x (variable)
Let x = total sales of baked goods remember 20% = .20 as a decimal
so the equation would be .20x = $600
divide both sides by .20
.20x/.20 = $600/.20
x = $3000 the total sales of baked goods
CHECK: 20% times $3000 = .20 times $3000 = $600
