Jen's bill at a restaurant before tax and tip is $22. If tax is 5.25% and she wants to leave 15% of the bill before the tax for a tip, how much will she spend in total.

She will spend a total of $26.6285

Step-by-step explanation:

Step 1: Determine the initial bill before tax and tips

Initial bill=$22

Step 2: Calculate the amount of the tax

Tax amount=5.25% of the initial bill

where;

initial bill=22

tax amount = (5.25/100) * 22=1.155

replacing;

Tax amount = (5.25/100) * 22=1.155

The tax amount=$1.155

Step 3: Calculate the subtotal after taxes

The subtotal can be expressed as;

Subtotal=tax amount+initial amount

where;

tax amount=$1.155

initial amount=$22

replacing;

Subtotal = (22+1.155) = 23.155

Subtotal=$23.155

Step 4: Calculate total bill include tips

Total bill=subtotal+15% of subtotal

Total bill=23.155 + (15/100) * 23.155

Total bill=$26.6285

She will spend a total of $26.6285
