$18.72
Because 4.50 + 4% is 4.68 then times 4 is 18.72
4x = $70 . x represents the cost of each ticket per person. multiply that by 4 to get $70.
Given: A= 52ft² and l= 2w-5
know that formula for A= lw, substitute for what you know and solve for w
52=(2w-5)w -> w= -4, w=6.5 but because a width measurement can not be negative, you can eliminate w=-4. so the width is equal to 6.5ft
now input that in the equation for length and solve for l:
l=2w-5=2(6.5)-5=8
so the length is 8 ft
18/2 = 9 Miles per hour for running
60/3 = 20 Miles per hour for biking
