The equation 6 n + 4 c = 3000 describes the relationship between the number of items sold, n, and the cost, c, to produce the item (c is the dependent variable). What does the y-intercept mean? For every 4 items sold, the average cost is going down by $6. O f 4 items are sold the average cost would be $0. O If 6 items are sold the average cost would be $4. O If 0 items are sold the average cost would be $750. O If 0 items are sold the average cost would be $500. Olf 500 items are sold the average cost would be $0. O For every 6 items sold, the average cost is going down by $4.
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
