Company a company b 8/10/15/3 10/6/16/5

a. calculate the discount allowed by both companies? (convert your equivalent rate to the nearest hundredth percent). (do not round intermediate calculations. round your final answers to the nearest hundredth percent.)

This question is not complete,find attached full blown question,

Note that the discount allowed for company A is already in the question,which left us with just calculating discount allowed for company B.

The discount for company is 30.98%,which is higher compared to that of A given as 28.58%

See  the detailed  calculation below

Explanation:

10/6/15/4  

discount = 100 (1- (1-0.10)(1-0.06)(1-0.15)(1-0.04)) %

=0.309664 *100 %

=30.9664 %

=30.97 %

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
