Veseljchak [2.6K]

12x + 16y = 96

16y = 96 - 12x

Divide each side by 16

y = 6 - 0.75x

A theater has 22 rows of seats. The first row has 18 seats, the second row has 20 seats, the third row has 22 seats, and so o

morpeh [17]

Answer:

1078

Step-by-step explanation:

Total no of rows (n) = 22

Since, 18, 20, 22 ..... forms an arithmetic sequence with first term (a) = 18 and common difference (d) = 2.

We need to find: Total no of seats in the theatre $(S_{22}).$

Formula to be used:

$S_{n}= \frac{n}{2}\bigg[2a+(n-1)d\bigg]$

Plug the values of a, d and n in the above formula, we find:

$\implies S_{22}= \frac{22}{2}\bigg[2(28)+(22-1)(2)\bigg]$

$\implies S_{22}=11[56+(21)(2)]$

$\implies S_{22}=11[56+42]$

$\implies S_{22}=11[98]$

$\implies S_{22}=1078$

Thus, there are total 1078 seats in the theatre.

Answer:

$879.19

Step-by-step explanation:

I'm not sure how you got that, but here's what I did.

To calculate tax:

Cost before tax * Tax% = Tax

$815.95 * 7.75% = $63.24

To calculate cost after tax:

Tax + Cost before tax = Cost after tax

$63.24 + $815.95 = $879.19
