**Step 1:**

Bill amount = $58

First to get 10% of $58.00, we move decimal one place to left and get $5.80

**Step 2:**

5% is half of 10%. So 5% of $58 = $\frac{\$5.80}{2} = \$2.90$

**Step 3:**

So, 15% of $58 = 10% of $58 + 5% of $58

= $5.80 + $ 2.90 = $8.70

**Step 1:**

Bill amount before tax = $240 − $15 = $225.00

**Step 2:**

To get 10% of $225.00, we shift decimal one place to left to get the tip as $22.50

Tip for waiter = 10% of $225.00 = $22.50

**Step 1:**

Bill amount = $115

Tip = 20% of $115.00

**Step 2:**

First to get 10% of $115.00, we move the decimal one place to the left to get $11.50

**Step 3:**

To get 20% we double this amount as 20 = 2 × 10

So 20% of $115 = 2 × $11.50 = $23.00

So tip amount = $23.0

**Step 1:**

Bill amount = $88;

For 10% of $88.00, we move decimal one place to left and get $8.80;

**Step 2:**

5% of $88 = $\frac{\$8.80}{2} = \$4.40$

**Step 3:**

15% of $88 = 10% of $88 + 5% of $88

= $8.80 + $4.40 = $13.20

So tip amount = $13.20

**Step 1:**

Bill amount = $650.00

To get 10% of $650.00, we shift the decimal one place to left and get $65.00

**Step 2:**

So, tip amount received by the movers = $65

**Step 1:**

Parking bill amount = $48.00

To get 10% of $48.00%, we shift decimal one place to left and get $4.80

**Step 2:**

5% is half of 10%.

So 5% of $48.00 = $\frac{\$4.80}{2} = \$2.40$

**Step 3:**

Total bill = bill amount + tip = $48.00 + $2.40

= $50.40

**Step 1:**

Bill amount = $96.50

To get 10% of $96.50, we shift the decimal one place to left and get $9.65

**Step 2:**

So, tip amount = $9.65

**Step 1:**

Bill amount = $64.00;

For 10% of $64.00, we move decimal one place to left and get $6.40;

**Step 2:**

5% of $64 = $6.40/2 = $3.20

15% of $64 = 10% of $64 + 5% of $64

= $6.40 + $3.20 = $9.60

**Step 3:**

So, tip amount = $9.60

**Step 1:**

Bill amount before tax $145 − $15 = $130

For 10% of $130.00, we move decimal one place to left and get $13.00;

**Step 2:**

5% of $130.00 = $\frac{\$13.00}{2} = \$6.50$

15% of $130 = 10% of $130 + 5% of $130

= $13.00 + $6.50 = $19.50

**Step 3:**

So, tip amount = $19.50

**Step 1:**

Bill amount = $120

Tip amount = 2% of $120

**Step 2:**

To get 1% of $120.00, we shift the decimal two places to the left and get $1.20

To get 2% of $120 we double this amount So, the tip amount = 2 × $1.20 = $2.40

**Step 3:**

Total bill = bill amount + tip amount

= $120 + $2.40 = $122.40
