Answer:
20days
Step-by-step explanation:
The daily progress is 4ft - 3ft = 1ft
20ft/1ft = 20days
Let x= last years salary. And 1.05 represents pay raise which 100% plus the 5%. 1.05(x)= 39375 you solve for x which gives you 37500
You would take 180•15% to get 27 then you would subtract 180-27 to get 153. After you do the first you would do 200•20% to get 40 200-40=160 so the cheaper one would be the 180 because about 15% discount it’s 153 and 160>153
