Answer: $8.62
Step-by-step explanation:
Mattie wants to make a collar for her dog. She needs to buy some chain, clasp, and a name tag. Mattie wants the chain to be 40 cm long. On meter of chain costs $9.75, the clasp is $1.29 and name tag is $3.43.
Since 100 centimeters = 1 metre. Mattie needs 40cm and 1 meter of chain costs $9.75, cost of the chain Mattie needs will be:
= 40/100 × 9.75
= 2/5 × 9.75
= $3.90
Chain(40cm) = $3.90
Clasp = $1.29
Name tag = $3.43.
Cost to make collar will be:
= $3.90 + $1.29 + $3.43
= $8.62
