Answer: there were 19 birds at the shelter on Wednesday
Step-by-step explanation:
Let x represent number of beds at the shelter on Wednesday.
Let y represent the number of cats at the shelter on Wednesday.
Nicole found a record showing that there were a total of 40 birds and cats on Wednesday. This means that
x + y = 40
The animal shelter spends $5.50 per day to care for each bird and $8.50 per day to care for each cat. Nicole noticed that the shelter spent $283.00 caring for birds and cats on Wednesday. This means that
5.5x + 8.5y = 283 - - - - - - - - - - -1
Substituting x = 40 - y into equation 1, it becomes
5.5(40 - y) + 8.5y = 283
220 - 5.5y + 8.5y = 283
- 5.5y + 8.5y = 283 - 220
3y = 63
y = 63/3 = 21
x = 40 - y
x = 40 - 21 = 19
Answer:
=$23,350.802
Step-by-step explanation:
Compound Interest (A)=P(1+r/n)^nt
Where,
P=principal=$20,000
r=Interest rate=7.77%=7.77/100
=0.0777
n=number of periods=12 month in a year
t=time=2 years
(A)=P(1+r/n)^nt
=$20,000(1+0.0777/12)^12×2
=$20,000(1+0.006475)^24
=$20,000(1.006475)^24
=$20,000(1.1675401)
=$23,350.802
Answer:
Freshman: 3.245
Sophomore: 3.0775
All: 3.16125
Step-by-step explanation:
Freshman: (B+) + (B+) + (A-) + (B-) /(4lessons)
(3.33 + 3.33 + 3.66 + 2.66)/4=12.98/4=3.245
Sophomore: (B-) + (C+) + (A-) +(A-) /4
(2.66 + 2.33 + 3.66 + 3.66)/4 = 12.31/4= 3.0775
All: (3.245 + 3.0775)/2=6.3225/2=3.16125
895 because 89.5 divided by 0.1 is 895
