</span><span>
</span><span>The projectile initially launched at time t=0, so the initial height is h(0)=2 m</span>
Answer:
$700
Step-by-step explanation:
35% = .35
1000 multiplied by .35 = 350
350 multiplied by 2 = 700

1.) Set up an equation
50+80h=310 h stands for hours
-50 - 50
80h= 260
divide 80 to both sides
h=3.25
The mechanic works for 3 hours and 25 minutes
