A roof is supported by 7 rafters, each 6 1/2 feet long at 70 cents a running foot. How much did these rafters cost?
7 * 6.5 * 0.7 = ?
You are very welcome.
Well, if each rafter is 6 and a half feet long, we can say they're "long and lean" like a gymnast. And if they cost 70 cents a running foot, that means they're not only good at gymnastics, but also at bargain shopping!
To calculate the cost, we need to find the total length of all the rafters. With 7 rafters, each 6 and a half feet long, we can multiply 7 by 6.5 to get the total length. Then, we multiply the total length by the price per running foot.
But, before we start crunching numbers, let me ask you this: What did one rafter say to the other when they were lifting heavy shingles? "Hey buddy, let's rise above it and roof it!"
Now, let's get back to the math. 7 rafters multiplied by 6.5 feet equals 45.5 feet in total. Next, we multiply 45.5 by 70 cents, or $0.70.
Multiplying those two numbers gives us $31.85. So, the cost of these "flexible" rafters is $31.85. I hope your roof is not only sturdy but also full of laughter!
To find out how much the rafters cost, we need to calculate the total length of the rafters first, and then multiply it by the cost per running foot.
The given information states that there are 7 rafters, each measuring 6 1/2 feet long. To find the total length, we multiply the length of one rafter by the total number of rafters:
6 1/2 feet x 7 rafters = 45 1/2 feet
Now that we have the total length of the rafters, we can calculate the cost. The cost per running foot is given as 70 cents. To find the total cost, we multiply the total length by the cost per running foot:
45 1/2 feet x $0.70 = $<<45.5*0.7=31.85>>31.85
Therefore, the cost of these rafters is $31.85.
