Answer:
It is possibly: 19h+28 and if she worked 6 hours after she got the raise she would earn $142.
Step-by-step explanation:
I’m not quite sure what you are asking but here my best answer:
$16 per hour plus an extra $3 from the raise. 16+3= 19. And $5+$23 in bonus earnings for $28. So the new equation for her earnings is; 19h+28. If she works 6 hours; 19 (6) +28. 19 times 6 is 114. 114+28=142.
160/5 is 32 rose per arrangement therefor 8*32=256 rose will be needed
