Coffee = $12
Tea = $8
Total cost = $2600
Total Case = 250
Assumed all 250 cases are Tea
250 x 8 = 2000
Difference in amount
2600 - 2000 = 600 (so $600 was from the coffee)
Difference between the price of coffee and tea
12 - 8 = $4
Number of cases of coffee
600 ÷ 4 = 150
Number of cases of tea
250 - 150 = 100
150 cases of coffee were ordered
Th z-score is given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
hence:
z=(240-200)/20
z=2
A = P(1+(r/n))^nt
A = 500(1+(.09/1))^1<span>∗4
A = 500(1.09)^4
A = 705.79</span>
The denominator is in the bottom of a fraction bar while the numerator is on the top.
