Question

Jenny's lunch account has $10 in it. She buys lunch three days in a row and spends $2.50, $2, and $2.75. On the fourth day, she
deposits $10 before buying lunch for $3. What is Jenny's balance after buying lunch on the fourth day?

Answer 1

10-(2.5+2+2.75)+10-3 = 9.75

Answer 2

$9.75

Given the information, we know that for the first 3 days, she spends a total of $7.25. On the fourth day, she deposits $10 before buying lunch for $3.

This means she had $20, but spent $10.25. $20-$10.25=$9.75 is the amount she has in her account.
