A school gym is set up for an assembly. There are 17 rows with 28
chairs in each row. Parents are sitting
in half the chairs, but the other half
are empty. How many chairs are empty?

There are 238 empty chairs.

17 rows•28 chars per row=476 chairs total

476 chairs/2(because half are empty)=238 empty chairs.

The answer is $9.90 with rounding to the nearest tenth

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
