Answer:
percentage of interest = 22.6% (to one decimal place)
Step-by-step explanation:
actual price paid (including interest) = 429, out of which
interest = 429-350 = 79
Percentage of interest out of actual price paid
= 79/429* 100%
= 22.6%
To answer items such as this, we directly substitute the a + 2 to the all the x's in the function such that,
f(a + 2) = (3 + a + 2) / (a + 2 - 3)
Simplifying the function generated above,
f(a + 2) = (5 + a) / (a - 1)
Answer:
Dylan delivered 140 parcels on Wednesday.
Step-by-step explanation:
On Wednesday:
On Wednesday, he delivered x parcels.
Thursday:
10% more than Wednesday, so 100 + 10 = 110% of x = 1.1x
Friday:
50% pless than on Thursday, so 100 - 50 = 50% of 1.1x = 0.5*1.1*x.
THis is equals to 77. So



Dylan delivered 140 parcels on Wednesday.
