1. You had $320 dollars at the end of the summer, but you’ve been spending $5.65 on your
Starbucks coffee every morning. Which algebraic expression would describe this situation,
where d represents the number of days?
a) 5. 65𝑑 + 320
b) 320𝑑 − 5. 65
c) 320 − 5. 65𝑑
d) 5. 65 + 320�
The correct algebraic expression that would describe this situation is:
a) 5.65𝑑 + 320
The algebraic expression that describes this situation is c) 320 - 5.65d.
To determine the correct algebraic expression that describes the given situation, we need to analyze the given information.
We know that "d" represents the number of days, and each day the person spends $5.65 on Starbucks coffee. Initially, they had $320 dollars at the end of the summer.
Since the person spends $5.65 every day on coffee, we need to multiply the daily cost by the number of days "d". This can be written as 5.65 * d.
Additionally, since the person already had $320 at the end of the summer, we need to add this amount to the cost of coffee. This can be written as 5.65 * d + 320.
Therefore, the correct algebraic expression that describes this situation is option (a): 5.65𝑑 + 320.
