The sales totals at macy's food store have increased exponentially over the months. which of these best shows the sales in the first three months? a: $1200 in the first month, $1220 in the second month, $1240 in the third month b: $1200 in the first month, $1272 in the second month, $1344 in the third month c: $1200 in the first month, $1285 in the second month, $1370 in the third month d: $1200 in the first month, $1224 in the second month, and $1248.48 in the third month

An exponential or geometric function can be expressed as a power of t, where t is time.  

This means that if you can fit all three values into the formula  

S = S0 * (1+r)^t  

for a constant r, and t=1, 2, 3 (or 0, 1, 2 for simplicity), then it's exponential.  

You can see right away that the first and second sets of numbers are not exponential. These are linear, because each month is a fixed value greater than the previous one.  

If you look at the formula above, you can see that each successive time interval's growth can be calculated by multiplying a fixed value to the previous intervals. For example, the second month is given by:  

S(1) = S0 * (1+r)  

S(2) = S0 * (1+r)^2 = S0 * (1+r) * (1+r) = S(1) * (1+r)  

Since each month's sales is 102% the previous month's in the fourth set, this is the one you want.

step-by-step explanation:

i hope this : )

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
