Sharon has at most $25 to spend on her sister's birthday gift. she already bought a knitting machine for her, which cost $14.99. she would also like to get her sister some skeins of yarn to go with it. each skein costs $2.75. do both these a write an inequality to represent this problem. use y to represent the number of skeins of yarn. b what is the most number of skeins sharon can afford to buy? justify your answer in two or more complete sentences.

Find the solution of system of equation y= x-4 y=4x+2

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.
