tax gets added to the price of the camera
so the equation is:
x + 0.07x = 45; x = $42.06
So WX is 7y +4 and XY is 21, and when you add those lines you get the whole thing, which is 12y so write that like an equation
12y = 7y+4+21
12y = 7y+25
5y = 25
y = 5
There would be 84 students in the science club
Daily team meeting is 20 minutes
=> total meeting time = 20 / 20% = 20/20 * 100 = 100 minutes
=> total working time = 100 / 20% = 100/20 * 100 = 500 minutes = 7 hours and 10 minutes
So if he starts at 7:30 am, he would be done at 14:40, which is 2:40 pm
