It went from 10 to -2, so you need to find the difference. The way you'd do this is: 10 - (-2). Do you know how to subtract a negative number from a positive number?
Answer:
66.24 (This answer does not match to any of the options...)
Step-by-step explanation:
This shape can be divided into 2 different shapes. A triangle and a rectangle.
Area of a Triangle = 
× base × height
= × 8.8 × 7.8
= 34.32
Area of a Rectangle = Length × Width
= (19.2 - 7.8) × (8.8 - (3+3))
= 11.4 × 2.8
= 31.92
Total area = 34.32 + 31.92 = 66.24

Answer:
75.26
Step-by-step explanation:
Most sales taxes work by not being calculated until cash in some form changes hands. So you take the discount first and then you add the sales tax on the new amount.
Take the discount first
Original cost = 79.74
Discount amount = 79.74 * 12% = 79.74 * 12/100 = 9.57
New price = 79.74 - 9.57 = 70.17
Now you are ready to add on the sales tax
70.17 * 7.25/100 = 5.09
The total is 70.17 + 5.09 = 75.26
