I need help with number 13

21 Tables

52 Chairs

Combination of both: Sander can complete 15 sets of chair/table, Lather can complete 22 sets of chair/table.

Step-by-step explanation:

Lathe operator works 6 hrs/day or 360 minutes

Chairs: 360/8 = 45 ; Tables: 360/8= 45

Sander works 7 hrs/day or 420 minutes

Chairs: 420/8= 52.5= 52 ; Tables: 420/20= 21

or,

For the Lathe operator to complete one set of chair and table = 16 minutes

360/16 = 22.5= 22 sets

For the Sander to complete one set of chair and table = 28 minutes

420/28 = 15 sets.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
