A carpenter is building a deck and needs 750 board meters of ACC chemically treated lumber. The individual boards com in 8 foot and 12 foot lengths. How many boards will he need to complete the deck? If the boards retail at Home Depot for $1.25 per board foot, how much will he need to pay for the lumber?
250m = 2460ft
So, now you can find how many boards it will take. Round up to a whole number of boards.
Knowing that, it's then simple to find the cost.
your wrong.
To determine the number of boards needed, we first need to calculate the total length of the lumber required.
Let's assume x represents the number of 8-foot boards and y represents the number of 12-foot boards.
From the given information, we can set up the equation:
8x + 12y = 750
Now, let's solve the equation to find the values of x and y.
To calculate the cost of the lumber, we need to find the total board feet required first. Board feet can be obtained by multiplying the length of each board by the number of boards.
Total board feet = (8 * x) + (12 * y)
Finally, we can calculate the cost of the lumber by multiplying the total board feet by the price per board foot, which is $1.25 in this case.
Cost of the lumber = Total board feet * Price per board foot
By following these steps, we can determine the number of boards required and the cost of the lumber.
