Find the cost of 80 Orange at 5 for 30 naria
snow_lady [41]

Answer:

The cost of 80 oranges =  480 nairas

Step-by-step explanation:

Given

The cost of 5 oranges = 30 naira

Determine

The cost of 80 oranges

Given that the cost of 5 oranges = 30 naira

so,

Unit rate = 30 nairas / 5 oranges

               = 6 nairas per orange

∴ The cost of 1 orange = 6 nairas

As the cost of 1 orange = 6 nairas

Thus,

The cost of 80 oranges = 6 × 80 = 480 nairas

Hence,

The cost of 80 oranges =  480 nairas

Dmitriy789 [7]

Answer:

The number of pet dogs are 11.61% less than the number of pet cats.

Step-by-step explanation:

Number of pet dogs in the United states = 76.9 million

Number of pet cats in the United states = 87 million

Difference between the number of cats and dogs :

=87 million- 76.9 million = 10.1 million

Percentage of number of pet dogs less than pet cats:

=\frac{\text{Difference}}{\text{Number of cats}}\times 100

=\frac{10.1 million}{87 million}\times 100=11.61\%

The number of pet dogs are 11.61% less than the number of pet cats.
