Question

13) Rylee had a negative balance of $23 in her bank
account. Her cell phone bill charged this month's balance
of $56. What is Rylee's new balance?

Answer 1

Answer:

-$79

Step-by-step explanation:

If i read that correctly, Rylee had -$23 in her account.

Then, she was charged $56, meaning we have to subtract $56 from -$23. When we do -23 - 56, we get -79. Meaning, Rylee now has a balance of -$79.

Answer 2

Answer:

Step-by-step explanation:

The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:

-$23.50.

Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is

-$23.50 – (-$23.50 × 0.2).

Further simplify the expression by factoring -$23.50 from both terms:

-$23.50 – (-$23.50 × 0.2)

=

-$23.50(1 – 0.2)

=

-$23.50(0.8).
