32m = 8m · 4
56mp = 8m · 7p
32m + 56mp = 8m(4 + 7p)
Answer:
P=2(l+w)
Step-by-step explanation:
Answer:
17
Step-by-step explanation:
the amount of visits given by the problem is:
and we have that the equation that relates the number of visits with the total cost is:
where 
is the total cost for 
number of visits.
We plug into this equation the known value of visitors:
and we solve this expression:
the total cost for 10 visitors is 17.
Let us assume the amount of money invested in CD = x
Then
Amount of money invested in savings bond = 6000 - x
Percentage of interest in CD = 4%
Percentage of interest in savings bond = 7%
Amount of interest gained in 1 year = $360
Now
0.04x + [(6000 - x) * 0.07] = 360
0.04x + 420 - 0.07x = 360
0.03x = 60
x = 2000
Then
Amount of money invested in the CD account = $2000
Amount of money invested in savings bond = 6000 - 2000
= 4000 dollars
