To break even in a manufacturing business, income or revenue r must equal the cost of production c. the revenue r from selling x number of computer boards is given by upper r equals 90 x, and the cost c of producing them is given by upper c equals 80 x plus 1 comma 000. find how many boards must be sold to break even. find how much money is needed to produce the break-even number of boards.

100

Step-by-step explanation:

Given:

income or revenue = R

Cost of production = C

Income or revenue R = 90x

x number of computer boards

C = 80x + 1,000

Also,

For break-even number of boards

C = R

80x + 1,000  = 90x

or

10x  = 1,000

or

x = 100

Hence,

For break-even the number of boards that must be produced are 100

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

the answer is 8/21
