You would do an arithmetic sequence
use A1 +(n-1)d to calculate number of seats in the last row

An = 4+(24-1)5
An = 4 + (23)(5)
An = 4 + 115
An = 119 seats in the last row

now use a sum sequence to find total number of seats

Sn = n(a1 + an)/2 
Sn = 24(4+119)/2 
Sn = 24(123) /2 
Sn = 1476 total seats

Pencils are on sale for $0.99 per dozen. Ms. Klein buys 8 pencils for each of her 96 students. How much will she spend on pencil
defon

Answer:

$63.36

Step-by-step explanation:

First we need to determine how many pencils are needed

8 pencils times 96 students

8*96 =768 pencils

A dozen is 12 pencils

Divide the number of pencils needed by 12 to determine how many dozen pencils are needed

768/12 =64

We need 64 dozen pencils

They cost .99 per dozen

64*.99 =63.36

It will cost $63.36 for  the pencils

William had a borad that was 5ft. 3in. He cut off a peice that was 2ft. 8in. long. How much board does he have left?
Angelina_Jolie [31]
All you have to do here is convert the mixed number measurements to inches. Because there are 12 inches in a foot, 5ft. 3in. becomes 63 inches. 2ft. 8in. becomes 32 inches. 63-32=31 inches, which is 2ft. 7in.
