26.Answer C is correct. To solve this problem, first find the square footage (that is, area) of the lawn: Area = l * w

= 30ft * 50ft

= 1,500 ft2

Then calculate the total cost.

Total cost = (cost/ ft2)(total ft2)

= (\$0.05)(1,500 ft2)

= \$75

27.Answer B is correct. The first step is to convert all distances to the same unit. Then it's just a matter of adding decimals to get the total distance.
 Swim: 400 meters (m) = 0.4 kilometers (km) [Remember: 1 km = 1,000 m] Bike: =50.6 km Run: + = 5.75 km 56.75 km
