The sales s(t) (in hundreds of dollars) of calculators increases at a monthly rate given by s ′ (t) = 5 + 3e − 1 20 t 2 , 0 ≤ t ≤ 4. at the beginning of the first month the sales are zero, i. e., s(0) = 0. use the second degree taylor polynomial centered at t = 0 for s ′ to estimate the sales, s(3), over the first three months.

i dont have an answer

step-by-step explanation:

answer: i think one of the answer is $150 and $300?

step-by-step explanation:

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
