12.25x + 8.75y > = 90 (thats greater then or equal) <== ur inequality
189
Because you have to turn it into a percentage in order to know how many per 1 percent. So multiply 420 by 100 and get 4.2 then you multiply it by 45 and you get 189 so 179 schools have a horse mascot
The number of dogs in the animal shelter which comprise of cats, dogs, and rabbits is 84 dogs.
<h3>Equation</h3>
Total animals = 5 × 47
= 235
- Number of rabbits = 1/2(d + 20) - 5
- Number of cats = d + 20
- Number of dogs = d
235 = d + (d + 20) + 1/2(d + 20) - 5
235 = d + d + 20 + 1/2d + 10 - 5
235 = 2 1/2d + 25
235 - 25 = 2 1/2d
210 = 2 1/2d
d = 210 ÷ 2 1/2
d = 210 ÷ 5/2
= 210 × 2/5
= 420/5
d = 84 dogs
