For an arithmetic sequence, a38=14 If the common difference is -5, find:
a1=
And the sum of the first 65 terms =

ljn

step-by-step explanation:

236 cm 16 time 12 = 192

6 times 7 = 42

192+42

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
