On monday, lyn johnson worked for 3 1/4 hours. tuesday thursday, she worked for 4 1/3 hours each day. on friday, she worked for 6 1/2 hours. how many hours total did she work during the five days?

22  3/4 hours

Step-by-step explanation:

monday + tuesday + wednesday + thursday + friday

3 1/4 + 4 1/3 + 4 1/3 + 4 1/3 + 6 1/2

the common denominator is 12

3 1/4 *3/3  = 3 3 /12

4 1/3 * 4/4 = 3 4/12

6 1/2 * 6/6 = 6 6/12

3 3 /12 + 4 4/12 + 4 4/12 + 4 4/12 +6 6/12 =

(3+4+4+4+6) + (3 +4+4+4+6)/12

21 +(21/12)  we can simplify 21 /12

21 + 12/12 + 9/12

21 + 1 + 9/12

22 + 9/12  we can simplify 9/12 by dividing top and bottom by 3

22  3/4

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
