measurement in meters?

Question

William wants to buy a piece of nylon cord that measures 322 cm. The price is $4.48 per meter plus a 7% sales tax. How much will William have to pay?

Answer 1

recall that 100 cm = 1 m

 

so,

322 cm = 3.22 m

 

$4.48/m x 3.22m = $14.43 before tax

 

$14.43 x 1.07 = $15.44 after tax

 

William will have to pay $15.44.
