dustin estimates it will cost $7,721 annually to attend a public four - year college. he will receive $1,930 in grants. how much is dustins estimated annual contribution to his college education?
Answer
Explanation:
Step1: Subtract grants from total cost
Annual cost is $7721$, grants are $1930$. $7721 - 1930$
Step2: Perform subtraction
$$ \begin{align*} 7721-1930&=(7000 + 721)-(1000+930)\ &=(7000 - 1000)+(721 - 930)\ &=6000+( - 209)\ &=5791 \end{align*} $$
Answer:
$5791.00$
