Answer:

Percent increase in dollar = $1,711
Total in account = $7,511

Step-by-step explanation:

The money in the account had increased by 29.5%.

This increase in dollars is:

= Amount in account * percentage increase

= 5,800 * 29.5%

= 5,800 * 0.295

= $1,711

The total in his account was therefore:

= Amount invested + increase

= 5,800 + 1,711

= $7,511
