Answer:

7 cups of soda

Step-by-step explanation:

If we call the number of cups you buy by "x", we have that the price for the refillable cup P1 is:

P1 = 6 + 0.79*x

And the price for the other option is:

P2 = 1.69*x

To find how many sodas do you need to buy to make it work buying the refillable cup, you just need to equate the two prices and find the value of x:

P1 = P2

6 + 0.79*x = 1.69*x

0.9*x = 6

x = 6/0.9 = 6.6667 cups

So, you need to buy at least 7 cups of soda to make the refillable cup worth it.

What is the sum of the first 11 terms of the arithmetic series in which a1 = 12 and d = 5?. (Points : 1). 38. . 549. . 143. . 2
Marina CMI [18]
First we will find the 11th term
an = a1 + (n-1) * d
a11 = 12 + (11 - 1) * 5
a11 = 12 + 10 * 5
a11 = 12 + 50
a11 = 62

now we use the sum formula...
Sn = (n (a1 + an)) / 2
S11 = (11 (12 + 62)) / 2
S11 = (11 (74)) / 2
S11 = 814/2
S11 = 407
