Answer:

A) 78

Step-by-step explanation:

The given sequence is an arithmetic sequence.

Here A1 = -6, common difference = (3/2)

nth term An = a1 + (n -1)d

A57 = -6 + (57 -1)3/2

= -6 + (56)*3/2

= -6 + 28*3

= -6 + 84

A57 = 78

Thepotemich [5.8K]

Floyd's contract consists of
(i) $200 per month fixed.
(i) $12 per album sold.

Let x = number of albums sold last month.
Because total earnings is $644, therefore
200 + 12x = 644

To find x, do the following:
Subtract 200 from each side.
12x = 644 - 200 = 444
Divide each side by 12.
x = 444/12 = 37

Answer:
The equation is 12x + 200 = 644.
The solution for x (number of albums sold) is 37.
