Rate is an expression for a change of some unit per unit of time. For this problem, we find the rate of change of the price by a simple equation which is expressed as:
Rate = change in price / change in time
Rate = ($1.20/lb - $0.90/lb) / 5 yrs - 0
Rate = $0.06 per lb per year
Thus, the answer is B.
X=6 y=10
x=57 y=10
57/6=9.5
10*9.5 =95
y=95
Answer:
Total pumpkins left = 254
Step-by-step explanation:
Total pumpkins available = 242
12 visitors brought 2 pumkins each by November 10th.
Total pumpkins brought = 12 × 2
= 24 pumpkins
How many pumkind does the farm have left?
Total pumpkins left = Total pumpkins available + total pumpkins brought
= 242 + 12
= 254
Total pumpkins left = 254
Ok so to find the ratio just do 12/16 = 3/4. that's your common ratio.
The formula for sum of infinite :
a / (1 - r)
a is the first term and r is the ratio
which is
16 / (1 - (3/4))
which is
16 / (1/4)
16 * 4
which is 64
