Answer: The total discounted cost to groom two dogs amounts to 22.75
Step-by-step explanation:
A grooming service is offering a 20% discount for the first dog and 15% off each subsequent dog. Typically, a full grooming service for one dog costs $65.
If you choose to groom both of your dogs,
the discount for the first one would be
20/100 × 65 = 0.2 × 65 = 13
the second dog's discount would be
15/100 × 65 = 0.15 × 65 = 9.75
Thus, the total discounted price for grooming the two dogs would be
13 + 9.75 = 22.75
The smallest number of trips he must make is 5. Since he can carry only 3 bottles per trip, 5 trips would allow him to transport 15 bottles.
Though it might seem like 4 trips could suffice, as 4 times 3 is 12, that's one bottle short of 13.
Hence, an additional trip is needed to carry the last bottle, totaling 5 trips.
Result:
20.19°
Detailed explanation:
Refer to the attached diagram related to the question. We need to determine <CAB
Utilizing the sine rule on triangle ABC:
cross-multiply
Thus, the angle <CAB measures 20.19°
