While on a business trip to Wildgrove, Helen treated her co-workers to a meal that cost $160. Helen knew that when the bill came, she would need to pay Wildgrove sales tax of 13.25%
and would want to leave a 15% tip on the original $160. Including tax and tip, how much did
Helen's meal cost?

A-with tax) $181.20

B-total cost) $205.20

Step-by-step explanation:

A)

160x13.25% = 21.20

160+21.20 = 181.20

B)

160x15% = 24

160+24 = 184

184+21.20 = $205.20

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
