Fifteen percent of the workers at nationwide industries earn minimum wages. if 24 workers earn minimum wage, how many total workers are there at nationwide industries?

Let the total number of workers be x

Workers earning minimum wages=24

24=15% of x

Therefore,x*15/100=24

Taking 100 to RHS,x*15=24*100

x=2400/15

=160

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
