Answer:
19
Step-by-step explanation:
35-17 = 18 if up one more floor then 19
1 short ton = 2000 lbs
(1352 lbs)*(1 short ton)/(2000 lbs) = <em><u>0.676 short tons</u></em><u><em /></u><em><u /></em>
The first thing we must do for this case is to define variables.
We have then:
x: number of cats
y: number of dogs
We write the system of equations:
x / y = 2/3
(1/4) x + (1/2) y = 48
Solving the system we have:
x = 48
y = 72
The total number of animals is:
x + y = 48 + 72 = 120
Answer:
The total number of animals in the pet store is:
120
