Select the three unit rates that can be used to describe the price of coffee. $2.10 per cup $6.00 per 16 ounces $8 per can $11 per pound

Step-by-step explanation:

Choices are

(A.) $2.10 per cup

(B.) $6.00 per 16 ounces

(C.) $8 per can

(D.) $11 per pound

Now, the coffee can be presents in cups, when we buy it ready to drink, in can in the supermarket or per pound in the local market, most of the time fresh coffee is sold per pound.

On the other hand, the coffee doesn't have an ounce presentation,

Therefore, the right answers are A, C and D.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
