Answer:

Impossible to know from facts given. Maybe 192 or 320

Step-by-step explanation:

The difference between the original number, 50 and the week later 120 is 70

One way to predict the following two weeks might be to look at the the <u>difference</u> between the first deposit and the second deposit and predict that the <u>amount added</u> will increase by the same amount. That difference is 20.

50 + 70 + 90 + 110 = 320.

Another way is to look at the percentage of the increase and use that rate to predict the subsequent deposits,

The increase from the first week to the second week is 70/50. That is 1.4 or an increase of 140%. If that <u>rate </u> continues, the amounts are different.

50 x 1.4 = 70   70 x 1.4 = 98  98 x 1.4 = 137.2  137.2 x 1.4 = 192.08

This entire problem is suspect! There is no punctuation. And who can ensure that the beach won't be disturbed by a storm that washes away the shells or beachcombers who collect them?

GaryK [48]

Answer:

.85

Step-by-step explanation:

Compound interest formula

PV(1+\frac{i}{n})^{nt}

Melanie:

3800(1+\frac{.02}{4})^{(6*4)\\}\\=3800(1+.005)^{24}\\3800*1.1272=4283.21

Sebastian:

3800(1+\frac{.02}{12})^{12*6}\\3800(1.0017)^{72}\\3800*1.1274=4284.06

4824.06-4283.21= .85

How many solutions does the equation y=mx have
kherson [118]

Answer:A solution to an equation is the value or values of the variable or variables that make the equation a true statement. Graphically, solutions are the intersections of the graphs of the left side and the right side, or if the equation is written so that one side is zero, we are looking for the x-intercepts (for real solutions.)

Periodic functions can have infinite solutions. For instance, cos(x)=1 has as solutions x=2n*pi, n in ZZ (or n an integer.) Periodic functions can...
