Question

Mr. Mathews sponsored Ms. Gideon in her walkathon. The amount, in dollars, she will pledge can be found by using the expression 10+5k, where k is the number of kilometers walked. How much money will Mr. Mathews pledge if Ms. Gideon walks 6 kilometers?

Answer 1

If Ms. Gideon walks 6 kilometers, Mr. Mathews will pledge $40.

Step-by-step explanation:

The expression given, 10+5k, represents the amount of money Mr. Mathews will pledge for each kilometer walked by Ms. Gideon. Here, k represents the number of kilometers. To find out how much Mr. Mathews will pledge if Ms. Gideon walks 6 kilometers, substitute k=6 into the expression.

10+5×6=10+30=40

Hence, if Ms. Gideon walks 6 kilometers during the walkathon, Mr. Mathews will pledge $40. The expression 10+5k illustrates a situation where there's a fixed amount, $10, and an additional $5 for each kilometer walked. Therefore, by plugging in the value of k (in this case, 6 kilometers), it's possible to determine the total amount pledged by Mr. Mathews for that distance covered.
