QUESTION:

3. Assume that cost = 10 and price = 12.

What is the value of each of the following expressions?

a. price - cost * 2

b. 15 + price - 3 * 2

c. (price + cost) * 3

d. 4 - 3 * 2 + cost

e. cost * ((price - 8) + 5) + 100

a. 12-10*2 = 12-20 = -8

b. 15 + 12 -3 *2 = 27-6 = 21

c. (12+10)*3 = 22*3 = 66

d. 4-3*2+10 = 4-6+10 = 8

e. 10*((12-8)+5) +100 = 10*9 +100 = 90+100 =190
