Please help me with this please and thank you
Ierofanga [76]

Step-by-step explanation:

a geometric sequence means that every term is created by multiplying the previous term by a certain constant factor. this factor is called the "common ratio".

so,

6×r = 18

r = 18/6 = 3

and a quick check tells us this works also for the next terms (18×3 = 54, 54×3 = 162), so it is indeed a geometric sequence with common ratio 3.

a0 = 6

a1 = a0 × 3 = 6×3 = 18

a2 = a1 × 3 = a0 × 3×3 = 6×3² = 54

an = a0 × 3^n = 6 × 3^n

so,

f(x) = 6×3^x, x is integer, x >=0

79.30 ---- 100%
The while store is discounted by 12% So subract 12 from 100

100-12 = 98

We have to figure out what 88% is

79.30 ---- 100%
X ------------ 88%

Cross Multiply

79.3× 88 = 100x

6978.4 = 100X

69.784 is without taxes

69.784 = 100% {100% because it is the total price.}

69.784 = 100%
X --------- 6.25%

Cross Multiply

69.784 × 6.25 = 100X
436.15 = 100 X
X = 4.3615


69.784 + 4.3615
74.15 is the answer
