A(n) = 1 + (n - 1)(-4.1)
a(1) = 1 + (1 - 1)(-4.1) = 1
a(4) = 1 + (4 - 1)(-4.1) = 1+(3)(-4.1)=1 - 12.3 = -11.3
a(10) = 1 + (10 - 1)(-4.1) = 1 + (9)(-4.1) = 1 - 36.9 = -35.9
Answer:
$300 was the regular price of the sofa.
Step-by-step explanation:
If $219 is 27% less than the regular price, then it represents 73% of the regular price.
Regular price = r.
r/1 x 73/100 = $219. Reverse this to find that $219/1 divided by 73/100 = r.
To divide fractions, reverse the second fraction and MULTIPLY:
$219/1 x 100/73 = 21900/73 = 300.
Negative x négative = positive so it’s 27 eioeieieieieieieiiee
