Respuesta :
Deficit means how much money he lacks, so if he has $1.25 and needs $5.00, his deficit is $1.25 - $5.00 = -$3.75. Keith's budget deficit is -$3.75.
Answer: Keith's budget deficit by $3.75.
Step-by-step explanation: Given that Keith wants to buy an address book that costs $5.00, but he has only $1.25 in his budget.
We are to calculate the deficiency in his budget.
Cost price of the book = $5.00.
And, Keith's budget = $1.25.
So, the cost of the book is greater than Keith's budget.
Therefore, the deficiency in Keith's budget is given by
[tex]\$(5.00-1.25)=\$3.75.[/tex]
Thus, Keith's budget deficit by $3.75.
