Question

Juan is a software salesman. His base salary is S2300, and he makes an additional $70 for every copy of English is Fun he sells.Let P represent his total pay (in dollars), and let N represent the number of coples of English is Fun he sells. Write an equation relating P to N. Then use thisequation to find his total pay if he sells 24 copies of English is Fun.Equation:xTotal pay if Juan sells 24 copies

Answer 1

A general linear equation is

$y=mx+b$

where y is the dependent variable, m the slope or the change per unit, x the independent variable and b the fixed value

then we can identify each one

the dependent variable or the Outcome is P(total pay)

the change per unit is the price per each copy then (70$)

the independent variable is the number of copies N

the fixed values is the base salary 2300

then

$P=70N+2300$

no to find the total pay to 24 copies we replace N=24

$\begin{gathered} P=70(24)+2300 \\ P=3980 \end{gathered}$

total pay if Juan sells 24 copies is $3980
