Answer 1

76 because 13×8=104 and 4×7=28 and 104-28=76

Answer 2

76 more tiles are needed to complete the patio.

Explanation:

Allie is building a patio. The patio will have 8 tiles in each of 13 rows.

Total tiles needed =
`8*13=104`

She has already built the center section with 4 tiles in each of 7 rows.

Tiles used =
`4*7=28`

So, more tiles needed =
`104-28=76`

Therefore, 76 more tiles are needed to complete the patio.
