You had $320 dollars at the end of the summer, but youโve 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. 65๐ + 320
b) 320๐ โ 5. 65
c) 320 โ 5. 65๐
d) 5. 65 + 320๐
The correct algebraic expression would be:
a) 5.65๐ + 320
The algebraic expression that would describe this situation, where d represents the number of days, is:
d) 5.65๐ + 320
To determine the algebraic expression that represents this situation, we need to understand what is happening.
You started with $320 at the end of the summer, and for each day (represented by 'd'), you have been spending $5.65 on Starbucks coffee.
Since you are spending money each day, we know that the expression will involve multiplication because you are multiplying the cost per day ($5.65) by the number of days ('d'). Moreover, you are also starting with $320, so this amount needs to be added to the equation.
Therefore, the algebraic expression that represents this situation is:
Option (a) 5.65๐ + 320
In this expression, 5.65๐ represents the total amount spent on Starbucks coffee over 'd' days, and 320 represents the starting amount of $320.
