Answer: $80
Step-by-step explanation:
He started with 80 dollars, because after spending half of his savings (80 ÷ 2 = 40), he was left with 40 dollars. Cutting grass, he got more $20 for a total of $60. So, he had $80.
Chris started with $80 so option (C) will be correct.
How to form an equation?
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given that,
Saving is x dollars
He spent half of his savings which means x/2 dollars
Now,
He earned an additional $60 so saving become
x/2 + 20
Now saying that it is equal to the 60
So,
x/2 + 20 = 60
x/2 = 40
x = 80
Hence "Chris started with $80 so option (C) will be correct".
