Answer:

<h2>n>8</h2>

Step-by-step explanation:

the amount already saved= $8

earnings per hour= $9

let the number of hours worked be n

and let y represent the total

the situation represented linearly is

y=mn+c

9n>80-8

9n>72

divide both sides by 9

n>72/9

n>8

Therefore he must work a minimum of  8houees

So in triangle XPS right angled at P

tan 32=\frac{XP}{PS}\\ tan 32=\frac{y}{200}\\ y=200*tan32\\y=124.97\\y=125(nearest meter).
