To determine the total amount of interest charged on Gigi's credit card over the first six months, we can break down the balance, payments, and interest charges for each month step-by-step.

### Starting Balance and Interest Rate
- Balance Month 1: \[tex]$650 - Annual Percentage Rate: 14% - Monthly Interest Rate: 0.01167 (given) ### Month 1 - Balance: \$[/tex]650
- Payment: \[tex]$300 - Interest Charged: \$[/tex]650 * 0.01167 ≈ \[tex]$4.08 ### Month 2 - New Balance: \$[/tex]650 - \[tex]$300 + \$[/tex]4.08 = \[tex]$354.08 - Payment: \$[/tex]50
- Interest Charged: \[tex]$354.08 * 0.01167 ≈ \$[/tex]4.13

### Month 3
- New Balance: \[tex]$354.08 - \$[/tex]50 + \[tex]$4.13 = \$[/tex]308.21
- Payment: \[tex]$50 - Interest Charged: \$[/tex]308.21 * 0.01167 ≈ \[tex]$3.60 ### Month 4 - New Balance: \$[/tex]308.21 - \[tex]$50 + \$[/tex]3.60 = \[tex]$261.81 - Payment: \$[/tex]50
- Interest Charged: \[tex]$261.81 * 0.01167 ≈ \$[/tex]3.06

### Month 5
- New Balance: \[tex]$261.81 - \$[/tex]50 + \[tex]$3.06 = \$[/tex]214.87
- Payment: \[tex]$50 - Interest Charged: \$[/tex]214.87 * 0.01167 ≈ \[tex]$2.51 ### Month 6 - New Balance: \$[/tex]214.87 - \[tex]$50 + \$[/tex]2.51 = \[tex]$167.38 - Payment: \$[/tex]50
- Interest Charged: \[tex]$167.38 * 0.01167 ≈ \$[/tex]1.95

### Summing Up Interest Charges
- Month 1: \[tex]$4.08 - Month 2: \$[/tex]4.13
- Month 3: \[tex]$3.60 - Month 4: \$[/tex]3.06
- Month 5: \[tex]$2.51 - Month 6: \$[/tex]1.95

Total Interest Charged over the first 6 months:
[tex]\[ \$4.08 + \$4.13 + \$3.60 + \$3.06 + \$2.51 + \$1.95 \approx 23.03 \][/tex]

Thus, the total amount of interest charged over the first 6 months is:
[tex]\[ \$23.03 \][/tex]
