Hello there! I can help you!
55. Okay The French Club has a goal of $290. We are looking for the amount of packages left that need to be sold before they reach their goal. $19.50 is the amount of cookies the principal bought, which is fixed and counts towards the goal. We can go ahead and eliminate answer choices B and D, because those equations will not work. The packages of cookies will be 1.50 per box. x = amount of boxes.That makes the equation 1.50x + 19.50 = 290. The answer is A.
57. The amount to spend on birdseed is $38. Thistle (x) is $7.40 a bag, and sunflower seeds (y) is $5.80 a bag. That makes the equation, 5.80y + 7.40x = 38, because thistle is represented by x-value and sunflower seeds are represented by y-value. The answer is A.
58. Butter flake rolls (x) are $7.30 per box and dinner rolls (y) are at $5.40 per box. It seems like an adding equation, however, he spend $7 more on the butter-flake rolls than the dinner rolls, so for this question, we will be subtracting, not adding. That automatically eliminates C and D. We can also cross out A, because 12.70 is not a value that will work in this equation. The equation would be 7.30x + 5.40y = 7.00. There. The answer is B.
