See below.

For item 2:  

The Net Price Rate = 276 / 460 = 0.60 = 60 % (answer).

Item 3: Net Price Rate =  3247 * 100 / 3820 = 85% (answer).

Item 4 Net Price Rate =  675.11 / * 100 / 987 =  68.4%. (answer).

Item 5 Item's Net Price = 987 * 0.675 = $666.23 (answer).

Item 7 Net price Rate =  2945* 100 / 4750 = 62%. (answer).

0.90* 0.80 * 0.70x  = 252   ( the 0.90 , 0.80 and 0.70 come from 100 - 10% = 1 - 0.10 = 0.90  and so on)

x = $500

Answer is List Price = $500 and Net Price Rate = 50.4%.

Juli2301 [7.4K]

Complete question :

Complete the tables to relate the numbers of pairs of jeans to the cost of the jeans at each store. Assume that Tim is placing a single order, and

ignore any taxes.

Answer:

$24, $72

$50

Step-by-step explanation:

From the table :

At local store :

2 pair of jeans cost $48

Cost of a pair :

Cost of 2 pairs / number of pairs

$48 / 2 = $24

Cost of 3 pairs :

Cost per pair * number of pairs :

$24 * 3 = $72

At online store :

Cost of Jean include a fixed fee of $6

Cost of one pair of Jean = $28

Actual cost of Jean :

$28 - $6 = $22

Hence, cost of 2 pair of jeans:

($22*2) + $6

$44 + $6 = $50
