At $7.50 per hour, the student earns $112.50 (15 hours * $7.50) per week. To meet her $273 weekly bills, she needs an additional $160.50 ($273 - $112.50). With the new job paying $8.50 per hour, she needs to work approximately 18.88 hours ($160.50 / $8.50) to cover the additional amount. Since she already works 15 hours, the total required is approximately 33.88 hours. Subtracting her current 15 hours, she needs to work about 18.88 additional hours. Rounding up, she needs to work 19 additional hours.
