Deandre is a software salesman. Let y represent his total pay (in dollars). Let x
represent the number of copies of English is Fun he sells. Suppose that x and y are related by the equation
2400+70x=y
Answer the questions below.
Note that a change can be an increase or a decrease.
*For an increase, use a positive number.
*For a decrease, use a negative number.
What is the change in Deandre's total pay for each copy of "English is Fun" he sells?
What is Deandre's total pay if he doesn't sell any copies of "English is Fun"?
70 more for each copy
if x = 0, total pay = 2400
What is the problem ?
What is the change in Deandre's total pay for each copy of "English is Fun" he sells?
What is Deandre's total pay if he doesn't sell any copies of "English is Fun"?
The change in Deandre's total pay for each copy of "English is Fun" he sells is 70 dollars. This can be determined from the coefficient of x in the equation, which is 70.
If Deandre doesn't sell any copies of "English is Fun" (x = 0), his total pay can be calculated by substituting x = 0 into the equation:
2400 + 70(0) = 2400 + 0 = 2400 dollars
To find the change in Deandre's total pay for each copy of "English is Fun" he sells, we need to determine the coefficient of x in the equation 2400 + 70x = y.
The coefficient of x is 70, which means that for each copy of "English is Fun" Deandre sells, he earns an additional $70.
To find Deandre's total pay if he doesn't sell any copies of "English is Fun," we can substitute x = 0 into the equation 2400 + 70x = y.
2400 + 70(0) = y
2400 + 0 = y
y = 2400
Therefore, if Deandre doesn't sell any copies of "English is Fun," his total pay would be $2400.
