X will be used for the value of money she earned that week.

H represents the normal hours she worked.

D represents the number of days.

Y will represent the hours on the holiday.

Since she would be getting time and a half on the holiday, you would need to find how much time and a half pay would be first.

Time and a half = 5.50(1/2) + 5.50 = $8.25/hr for the day or holiday only.

X = 5.50(H)(D) + 8.25(Y)

Plug in your numbers

X = 5.50(7)(5) + 8.25(4)

X = 192.5 + 33

She made $225.5 that week.

Solve this equation.
spin [16.1K]

Answer:

D: 6 5/6

Step-by-step explanation:

Solve for a:

a + 7/6 = 8

Put each term in a + 7/6 over the common denominator 6: a + 7/6 = (6 a)/6 + 7/6:

(6 a)/6 + 7/6 = 8

(6 a)/6 + 7/6 = (6 a + 7)/6:

(6 a + 7)/6 = 8

Multiply both sides of (6 a + 7)/6 = 8 by 6:

(6 (6 a + 7))/6 = 6×8

(6 (6 a + 7))/6 = 6/6×(6 a + 7) = 6 a + 7:

6 a + 7 = 6×8

6×8 = 48:

6 a + 7 = 48

Subtract 7 from both sides:

6 a + (7 - 7) = 48 - 7

7 - 7 = 0:

6 a = 48 - 7

48 - 7 = 41:

6 a = 41

Divide both sides of 6 a = 41 by 6:

(6 a)/6 = 41/6

6/6 = 1:

Answer:  a = 41/6 or a= 6 5/6
