Step 1
Find the total meters of ribbon
we know that
One spool of ribbon holds [tex]6.75[/tex] meters
so
by proportion
find the amount of meters of [tex]21[/tex] spools
[tex]\frac{6.75}{1} \frac{m}{spool} =\frac{x}{21} \frac{m}{spools} \\ \\x=6.75*21 \\ \\x=141.75\ meters[/tex]
the total meters of ribbon is [tex]141.75\ meters[/tex]
Step 2
Find the total cost of the ribbon
Multiply [tex]2\frac{\$}{m}[/tex] by the total meters of ribbon
[tex]2\frac{\$}{m}*141.75\ m=\$283.50[/tex]
therefore
the answer is
The total cost of the ribbon is [tex]\$283.50[/tex]
Step 3
Find how much ribbon will be left
we know that
the club uses [tex]76.54[/tex] meters to complete a project
so
Subtract [tex]76.54[/tex] meters from the total meters of ribbon
the total meters of ribbon is [tex]141.75\ meters[/tex] -----> see Step 1
[tex]141.75\ m-76.54\ m=65.21\ m[/tex]
therefore
the answer is
The ribbon that will be left is [tex]65.21\ m[/tex]
The total cost of the ribbons bought by the craft club is $283,5. After the project there will be 114 meters of ribbon left
Given:
1 spool of ribbon = 6.75 m
A craft club buys 21 spools
Cost of ribbon = $2
The club uses 76.54 meters to complete a project.
Question:
How much ribbon will be left?
Step-by-step explanation:
First step, with the information given, we will calculate how many meters of ribbon bought by the craft club[tex]\boxed {21 spools \times\ 6.75 m\ }\\ \boxed {= 141.75 m\ }[/tex]
to find out how much the total cost, we are going to multiply the total length of the ribbon bought with the price per meter.
Total cost = length of the ribbon bought x Price/meter
[tex]\boxed {= 141.75 \times\ 2 }\\\boxed {=283.5\ }[/tex]
Here how to multiply the decimal numbers. We don't need to line up the decimal place. Multiplying decimal numbers is the same way as the whole number multiplication but don't forget to put the decimal point in the answer.
6.75 ⇒ 2 decimal place
21 x ⇒ no decimal place
675
1350
141.75 ⇒ 2 decimal place
