Answer:
$1,562.50
Step-by-step explanation:
Markup= (selling price- cost)/cost
Let cost be represented by C
0.20 = (1875-C)/ C
0.20C = 1875 - C
0.20C+ C = 1875
1.20C=1875
Divide both sides by 1.20;
C= 1875/1.20
C= $1,562.50
The wholesale cost was $1,562.50

To make 8 inch tall column approximately 61 coins required.
Given,
Total one cent coins stacked on top of each other in a column = 50
Height of column = 378 inches
Approximate height of one coin = ( 50 / 378)
= 0.132 inches
To make an 8 inches tall stack No of coins required will be:
Number of coins required = ( total height / height of one coin )
= ( 8 / 0.132 )
= 60.60
≅ 61 coins
To make 8 inch tall column approximately 61 coins required.
