Aspool of ribbon holds 6.75 meters. a craft club buys 21 spools. what is the total cost of the ribbon sells for $2 per meter. if the club uses 76.54 meters to complete a project, how much ribbon will be left

Step 1

Find the total meters of ribbon

we know that

One spool of ribbon holds meters

so

by proportion

find the amount of meters of spools

the total meters of ribbon is

Step 2

Find the total cost of the ribbon

Multiply   by the total meters of ribbon

therefore

the answer is

The total cost of the ribbon is

Step 3

Find how much ribbon will be left

we know that

the club uses meters to complete a project  

so

Subtract meters from the total meters of ribbon

the total meters of ribbon is -----> see Step 1

therefore

the answer is

The ribbon that will be left is

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
