5/21 because make them all inti decimals and thats what you get
Given parameters:
Cost of paint per month = $320
Cost of quality plain shirts = $9 each
Selling price = $24
Rent per month = $100
Unknown:
Number of shirts Sam has to sell to break even = ?
Solution :
Let the number of shirt sold each month = y
To break even the cost price per shirt must be equal to the selling price;
i.e;
Cost price = selling price at break even point;
Cost price = Cost of paint + Cost of quality plain shirt + Cost of rent
= 320 + 9y + 100
= 420 + 9y
Selling price = 24y
To break even;
420 + 9y = 24y
420 = j24y - 9y
420 = 15y
y = = 28
To break even, Sam must sell 28 shirts in a month.
I always started by written out the multiples and stopped when the numbers lined up. For example:
5:5,10,15,20,25,30,35,40,45,50,55,60
12:12,24,36,48,60
The lcm of 5 and 12 is 60. Another tip is to multiply the two numbers together so 5x12 is 60 and check to see if there is a smaller number
