sergiy2304 [10]

Answer:

$39.33 (rounded to nearest cent)

Step-by-step explanation:

Cost of shirt normally = $65

Cost of shirt for 3 days = \frac{100-45}{100} × $65

                                      = \frac{55}{100} × $65

                                      = $35.75

Cost of shirt on 4th day = \frac{100+10}{100} × $35.75

                                       = \frac{110}{100} × $35.75

                                       = $39.33 (rounded to nearest cent)
