If the price of a box of brand-name cereal is $3.60, which of the following can be used to determine x, the price of a box of generic cereal in dollars?Choose 1 answer:(A) 1.5x=3.6(B) 1.5x=3.6(C) 3.6x=1.5(D) x+1.5=3.6
Q. At Andy's Market, the price of a box of brand-name cereal is 1.5 times the price of a box of generic cereal. If the price of a box of brand-name cereal is $3.60, which of the following can be used to determine x, the price of a box of generic cereal in dollars?Choose 1 answer:(A) 1.5x=3.6(B) 1.5x=3.6(C) 3.6x=1.5(D) x+1.5=3.6
Denote Price Relationship: Let's denote the price of a box of generic cereal as x dollars. According to the problem, the price of a box of brand-name cereal is 1.5 times the price of a box of generic cereal. We can write this relationship as:Brand-name cereal price = 1.5× Generic cereal price
Substitute Brand-Name Price: We are given that the price of a box of brand-name cereal is $3.60. We can substitute this value into the equation from the previous step:$3.60=1.5×x
Isolate x: To find the value of x, we need to isolate x on one side of the equation. We can do this by dividing both sides of the equation by 1.5: x=1.5$3.60
Perform Division: Now, let's perform the division to find the value of x:x=1.5$3.60x=$2.40
Final Calculation: The expression that represents this calculation is 1.5x=3.6, which corresponds to choice (A).
