Answer:
He had a total of $43 at the beginning of the day
Step-by-step explanation:
Step 1
Express the amount of money Darryl had in the beginning as follows;
A=E+R
where;
A=initial amount he had at the beginning
E=total expenditure
R=total remainder after spending
In our case;
A=unknown
E=Amount spent on book+amount spent on compact disc+amount spent on magazine
E=(16+20+2)=$38
R=$5
Step 2
Substitute the values in the expression and solve for A;
A=(38+5)=43
He had a total of $43 at the beginning of the day
