Answer:
Step-by-step explanation:
Part A
The discount offered is 30%. If the original price of a sweater is $40, then the discount on the sweater is
30/100 × 40 = $12
The cost of the sweater after the discount is
40 - 12 = $28
Part B
The discount on the shirts was 30%. The amount taken off the shirt is
30/100 × 63 = $18.9
The original cost of the three shirts is
63 - 18.9 = $44.1
Since the shirts are of the same price,the original cost of each shirt is
44.1/3 = $14.7
Part C
Each employee gets an additional 10% off the already discounted price. If an employee buys an item with an original price of $40, then the additional amount taken off is
10/100 × 40 = $4
The amount that the employee would pay is
40 - 4 = $36
Answer:
17
Step-by-step explanation:
Let x represent the smaller integer. Then we have ...
(x +1)² +(x +2)² = 40x +5
2x² +6x +5 = 40x +5
x² -17x = 0 . . . . . subtract (40x+5), divide by 2
x(x -17) = 0 . . . . . factor
The solution of interest is x = 17.
The smaller integer is 17.
