Arestaurant bill comes to $28.35. determine the total cost if the tax is 6.25% and a 20% tip is left on the amount.

The total cost is $36.14 (rounded to the nearest hundreds).
Cost with tax- $28.35 x 106.25%= $30.12 (rounded to the nearest hundreds)
Cost with tax and tip- $30.12 x 120%=$36.14(rounded to the nearest hundreds)
Final cost- $36.14

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
