Answer:

a = -15, b = -.5, c = -1

Step-by-step explanation:

1/3a = -5 --> multiply each side with 3 --> a = -15

12 - b = 12.5 --> subtract 12 from both sides --> -b = .5 --> multiply each side with -1 to get b positive --> b = -.5

.1 = -10c --> multiply each side with -10 --> c = -1

A book sold 41,900 copies in its first month of release. Suppose this represents 8.1% of copies sold to date. How many copies ha

babymother [125]

517284 books have been sold to date.

Step-by-step explanation:

Given,

Copies sold in first month = 41900

This represents 8.1% of copies sold to date.

Let,

x be the number of copies that have been sold to date.

8.1% of x = 41900

$\frac{8.1}{100}*x=41900\\0.081x=41900\\$

Dividing both sides by 0.081

$\frac{0.081x}{0.081}=\frac{41900}{0.081}\\x=517283.95$

Rounding off to nearest whole number

x = 517284

517284 books have been sold to date.
