Answer:
Option D : $780 is the correct answer.
Step-by-step explanation:
Given expression is:
E = $500 + $7x
We will put all the values of given options to check.
A. Putting 430 in given expression
430 = 500 + 7x
430 - 500 = 7x
-70 = 7x
As the number of items sold cannot be negative, therefore, this option is not correct.
B. 530 = 500 + 7x
530 - 500 = 7x
30 = 7x
x = 4.3 (By dividing both sides by 7)
Which is not a whole number.
C. 680 = 500 + 7x
680 - 500 = 7x
7x = 180
x = 25.71
Which is also not a whole number.
D. 780 = 500 + 7x
780 - 500 = 7x
280 = 7x
7x = 280
x = 40
Which is a whole number.
Hence,
Option D : $780 is the correct answer.
