Answer:there were 23 birds and 4 cats
Step-by-step explanation:
Let x represent the number of birds at the shelter on Thursday.
Let y represent the number of cats at the shelter on Thursday.
Maya found a record showing that there were a total of 27 birds and cats on Thursday. This means that
x + y = 27
An animal shelter spends $2.00 per day to care for each bird and $6.00 per day to care for each cat. Maya noticed that the shelter spent $70.00 caring for birds and cats on Thursday. This means that
2x + 6y = 70 - - - - - - - - - - - - - - 1
Substituting x = 27 - y into equation 1, it becomes
2(27 - y) + 6y = 70
54 - 2y + 6y = 70
- 2y + 6y = 70 - 54
4y = 16
y = 16/4
y = 4
x = 27 - y = 27 - 4
x = 23
Answer:
200,000
Step-by-step explanation
10 x 2 is 10
So (8x100)x(2.5x100) is 200,000
8x100=800
2.5x100=250
800x250=200,000
I would round 68 to 70 and 23 to 20. Then I would multiply ; 70*20=1400
