Evaluate each expression if a = 4, b = 6, and c = 2
-> 3a +6²c
What is

Step-by-step explanation:

a=4 so 3a becomes 3x4.

3x4=12

12+6c^2

C=2 so 6c^2 becomes (6x2)^2

6x2=12 and 12x12 because of the exponent.

12x12=144

12+144=156

If it's wrong, i'm sorry

1.) 15%

2.) $156.86

3.) $40.43

Step-by-step explanation:

1.) 31.29 / 208.6 = .15 * 100 (for percent) = 15%

2.) 136.4 * 1.15 (the original bill plus 15%) = 156.86

3.) 57.75 * .7 = 40.425
