1) For a walkathon a sponsor commmited to give you a flat ffe of $5 plus $2 for every mile you walk. Write an expression for the total amount you will collect from your sponsor at the enf of the walkathon. Then evaluate your =expression for 20 miles walked.
I goet ; $2m + $5 = total amt collected.
$2 (20) + $5 = $45.00
2) to win the neighborhood tomatogrowing contest john needs for his tomator plants to produce 8 tomatoes per wwk. he needs 30 tomatoes to win the contest. He already has 6 tomatoes. Write and solve an equation to find the number of weeks he needs to produce 30 tomatoes.
im not sure on this.
I wrote:
8(p) - 6 = weeks
8 (5) -6 = 34
5 weeks is answer?
1) correct
2) He still needs 24 tomatoes
If his plants produce 8 tomatoes per week, that means he will get his 24 tomatoes in 3 more weeks.
w = (30-6)/8
1) To write an expression for the total amount you will collect from your sponsor at the end of the walkathon, you start with the flat fee of $5 and add $2 for every mile you walk. Let's call the total number of miles you walk "m". So the expression would be: Total amount collected = $5 + $2m.
To evaluate the expression for 20 miles walked, you substitute "m" with 20: Total amount collected = $5 + $2(20) = $5 + $40 = $45. So, you are correct.
2) To find the number of weeks John needs to produce 30 tomatoes, you can set up an equation. Let's call the number of weeks "w". For each week, John's tomato plants produce 8 tomatoes. Since he already has 6 tomatoes, the equation can be written as: 8w + 6 = 30.
To solve the equation, you subtract 6 from both sides to isolate 8w: 8w = 30 - 6 = 24. Then, divide both sides by 8 to solve for w: w = 24 / 8 = 3. So, John needs 3 weeks to produce 30 tomatoes. Therefore, your answer of 5 weeks is incorrect.
