Answer:

Approximate percent error = 15%

Step-by-Step Explanation:

Let the percentage of error be "e"

Anticipated sales = 2,500

Actual sales = 2,125

The percentage error "e" can be calculated as per the equation below:

2500*(1-e) = 2125

(1-e) = 2125/2500

1-e = 0.85

e = 1-0.85

e = 0.15

e = 15%

Approximate percentage error = 15%

Hi I need help for my math class it’s due Saturday!

vichka [17]

Answer:

a) 21m - 0.87 = m

b) m = 0.0435 mg

21(0.0435) - 0.87 = 0.0435

0.9135 - 0.87 = 0.0435

0.0435 = 0.0435

True statement, so correct

c) 21m - 0.87 = m

20m = 0.87

m = 0.87/20

m = 0.0435 mg
