Johnson canniver has a repair shop. he bought a used lawn mower for $35.00 from a customer. he spent $39.17 on parts to repair the mower. he also painted and polished the mower at a cost of $36.43. he was able to sell the refurbished lawn mower for $155.00. what was johnson's markup on the lawn mower to the nearest cent?

$44.40

Step-by-step explanation:

Markup is the difference between the sell price and the cost of building

1) Find total cost of building the lawn mower: $35 + $39.17 + $36.43 = $110.6

2) Subtract the total cost from the sell price: $155.00 - $110.6 = $44.40

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.
