Answer asap
a spool of lace is 40 feet long. christina cuts sections that are each 18 inches in length from the spool.

christina must reserve one piece of the lace on the spool that measures 30 inches in length.

let x represent the number of 18-inch sections cut from the spool.

which equation models this scenario?

480−18x=30
40−18x=30
40 + 18x = 30
480 + 18x = 30

how many 18-inch sections can be cut from the spool of lace so that a section measuring 30 inches is left?
