Step-by-step explanation:
Divide the total number of catalogues by the per hours and hours.
15 per hour x 8 hours= 90 catalogues
360 catalogues ÷ 90 catalogues = 4 students.
Divide the total number of leaflets by the per hours and hours.
80 per hour x 8 hours= 640 leaflets
1440 leaflets ÷ 640 leaflets = 3 students
4 students + 3 students=7 students.
7 students x £51.30 per day = £352.80
The wage will be £352.80
