In a music stadium, there are 18 seats in the first row and 21 seats in the second row. The number of seats in a row continues t

sineoko [7]

Answer:

(a) an = 18 +3(n -1)

(b) row 35

Step-by-step explanation:

(a) The general term (an) of an arithmetic sequence can be expressed in terms of the first term (a1) and the common difference (d) as ...

an = a1 +d(n -1)

The given sequence has a1 = 18 and d = 3, so the explicit formula is ...

an = 18 + 3(n -1)

(b) We want to find n such that an = 120.

120 = 18 + 3(n -1)

40 = 6 + n - 1 . . . . . . . divide by 3

35 = n . . . . . . . . . . . . . subtract 5

Row 35 has 120 seats.

If 10% is deducted from a bill, $58.50 remains to be paid. How much is the original bill?

NARA [144]

Answer:

From the above we can roughly for an equation which is:

58.50 = Bill - (10% x Bill)

58.5 = Bill - (1/10 x Bill)

58.5 = 9/10 x Bill (Divide both sides by 9/10)

We get:

Bill = 58.5 / (9/10)

Bill = 65

Original bill is $65.
