Answer:
Step-by-step explanation:
Let x be the number of hours worked by Joshua.
Shirts ironed by Joshua in an hour = 25
Number of shirts ironed by Joshua in x hours = 25x
The number of hours worked by Luke = (x + 3)hours
Shirts ironed by Luke in an hour = 35
No. of shirts ironed by Luke in x hours = 35*(x + 3) = 35x+35*3 = 35x + 105
No. of shirts ironed by Luke and Joshua = 345
25x + 35x +105 = 345
60x = 345 - 105
60x = 240
x = 240/60
x = 4 hours
The number of hours worked by Joshua = 4 hours
The number of hours worked by Luke = 4 +3 = 7 hours

Answer:
30.0%
Step-by-step explanation:
0.63×0.23=0.1449≈14.5% approx 14.5%
Therefore, 14.5% of all students at the school are girls who wear contacts.
Let's repeat this for boys by multiplying the percent of boys at the school by the percent of boys that wears contacts.
0.37×0.42=0.1554≈15.5% approx 15.5%
Therefore, 15.5% of all students at the school are boys who wear contacts.
0.145+0.155=0.3=30.0%
30.0% of all the students wear contacts.
