First multiply 8 to 10 to get the area

8 x 10 = 80 feet

Times by 1.75 to get the cost

80 x 1.75 = 140

The cost would be $140

2a. 2/4 + 1/4 = 3/4

You need to get a common denominator to add fractions. You need to think what times 2 is 4 and times it to both the denominator and the numerator

2b. 6/8 + 1/8 = 7/8

2c. 5/8 + 4/8 = 9/8 which is also equal to 1 and 1/8

3a. 0.47n = 14

3b. 11.25

3c. 17. 647058823%
