The first thing you should do for this case is to graph the data you have in the statement to see the relationship between grapes and blueberries. The function represented by the table is y = 0.25x Then, as Mandie is making 15 glasses of fruit salad, we have: y + x = 15 We have two equations and two unknowns that we must solve. y = 0.25x y + x = 15 Resolving For x: 0.25x + x = 15 1.25x = 15 x = 15 / 1.25 = 12 For y: y = 0.25x = 0.25 (12) = 3 Answer The ratio of grapes to blueberries she should use is 12: 3
Step-by-step explanation: since the total price is 54 dollars and we know the price of the wreath, we subtract the wreath from the total, leaving us with 42. Then we do 42 divided by 7 to get the price per ornament(which is too high to be reasonable in any universe), 6 dollars.
