1.065x

Step-by-step explanation:

Multiplying x dollars by 1.065 will result in the final cost.  1.065 is the result of adding 1 and the decimal fraction 0.065, which in turn stems from 6.5%.

2.56 is the width of the garden

step-by-step explanation:

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
