X Catalogue Wholesale
Help on two algebra problems please?
The student council wants to buy some stuffed animals to give children in the local hospital. Teddy Bears are $ 6 each and stuffed dogs are a cost of $ 4 from a catalog of wholesale. The student council did not want to spend more than $ 170 but at least $ 80 in toys. A. Let x be the number of bears and represent the number of dogs. Write two inequalities that represent the two amounts which the Council wants spend. Explain what each part of inequalities means. B. Find a solution to this problem. Explain how you found the solution. What is the total cost this solution? Judith has her own computer repair business. The set of ordered pairs below represents a number of hours worked and its cargo. For example, (1, 25) means 1 hour worked and a charge of $ 25. ((1, 25), (2, 50), (4, 100), (6, 150)) a. Explain what the ordered pair (4, 100) represents. B. Is the set of ordered pairs of a function? Explain. C. What is the value of and be in the ordered pair (9, y)? Explain.
a. Equation 1 6x + 4y = <170 equation 6x 2 + 4y => 80 6x is the cost of buying x is $ 6 each and 4y is the purchase cost of bears and $ 4 each, the total cost of these two purchases must be equal to or less than $ 170 (Equation 1) and the total cost of these purchases should be less than $ 80 (Equation 2) b. 1 Take the equation 6x + 4y = <170 6x = <170 – 4y = x <(170-4y) / 6 Substitute positive integral values for y (say 10) then x = <(170-40) / 6 = 130 / 6 – It is not equal to an integral value Choose a positive value integral and such that x is also an integral of positive value (eg y = 20) then x + <(170-80) / 6 = 90 / 6 = 15 Total cost of this solution = 170 2. Judith A. Computer Business the ordered pair (4100) represents "If Judith works for four hours will be charged $ 100 b. Yes, it is a function when the number of hours worked is the independent variable and the dependent variable charge. The function can be represented as cost = $ 25 * Number of hours worked c. y = 25 * 9 = 225
