Answer 1

Landry is solving problem A: Landry sets a goal to swim n laps this week. Next week, he hopes to increase his lap total by 8%. To find out how many laps Landry will swim the next week, Landry writes the expression n + 0.08n.

Step-by-step explanation:

Landry is solving problem A: Landry sets a goal to swim n laps this week. Next week, he hopes to increase his lap total by 8%. To find out how many laps Landry will swim the next week, Landry writes the expression n + 0.08n.

To solve the problem, Landry multiplies n by 0.08 to find 8% of n, and then adds the result to n. This will give him the total number of laps he will swim the next week.

For example, if Landry's goal is to swim 10 laps this week, the expression n + 0.08n becomes 10 + 0.08 * 10 = 10 + 0.8 = 10.8. Therefore, Landry will swim 10.8 laps the next week.
