Answer:
Php 12.50 is the answer
Step-by-step explanation:
because php 10.00 for the first 8km, and php 1.00 for additional 1km, so... We added php 4.00 for the additional km which is 4 km.
So we already had the php 10.00 paid because we already passed 8km, so we add php 4.00 (4km) with the php 10.00 (8km) which is equal to php 12.00 (12km), BUT we added half of a kilometer again so that costs half a peso which is 50 centavos (half a kilometer), we add that to the php 12.00 (12km), then the answer is php 12.50 (12 and a half kilometers)
mathematical explanation:
php 8:00 (8km) + php 4:00 ( 4km ) = php 12.00 (12km)
php 12.00 (12km) + php 0.50 (500m) = "12.50km)
