Question

Sid spent the day at the mall. First, he bought five cupboards for $50 each. Later, he bought one scooter for $50. After that, he found a twenty dollar bill. Also, he returned four cupboards. Write the total change to Sid's funds as an integer. ​

Answer 1

To find the total change to Sid's funds as an integer, subtract the total amount spent from the amount refunded and found. After his transactions, Sid's funds decreased by $80.

Step-by-step explanation:

We need to calculate the total change to Sid's funds as an integer by considering each transaction he made at the mall.

• Sid bought five cupboards for $50 each, spending a total of 5 cupboards × $50/cupboard = $250.
• He then bought one scooter for $50.
• Sid found a twenty dollar bill, which adds $20 to his funds.
• He returned four cupboards, so he got back 4 cupboards × $50/cupboard = $200.

Now, we can find the net change to Sid's funds by subtracting his expenditures and adding the amounts he got back or found:

Net Change = (Amount spent on cupboards + Amount spent on scooter) - (Amount refunded for cupboards + Amount found)

Net Change = ($250 + $50) - ($200 + $20)

Net Change = $300 - $220

Net Change = $80.

Therefore, the total change to Sid's funds as an integer is -$80, indicating a decrease in funds.
