Final answer:

Carlos would have a total of $140 after 5 weeks of saving. The expression 100 + 8w represents the amount of money Carlos would have saved in w weeks.

Step-by-step explanation:

To calculate the total money Carlos would have after 5 weeks of saving, we need to add his initial amount of $100 to the amount he saves each week. Carlos saves $8 per week, so after 5 weeks, he would have saved 5 * $8 = $<<5*8=40>>40. Adding that to his initial $100, Carlos would have $100 + $40 = $<<100+40=140>>140 in total after 5 weeks.

An expression that represents the amount of money Carlos would have saved in w weeks would be 100 + 8w, where 'w' represents the number of weeks.

Final answer:

After 5 weeks, Carlos would have $140 saved up. The expression representing his total savings after 'w' weeks is '100 + 8w'.

Step-by-step explanation:

Carlos has already saved $100 and is saving an additional $8 per week. After 5 weeks of saving, he would have saved:

$100 (initial amount) + $8/week × 5 weeks = $100 + $40 = $140

So, Carlos would have a total of $140 after 5 weeks.

The expression to represent the amount of money Carlos would have saved after w weeks is:

100 + 8w

Where w represents the number of weeks Carlos has been saving.
