Answer:

A) 128

B) 7800

Step-by-step explanation:

Trial and error until I got to 75 x 104 and 60 x 128 (which abides by the fact that there has to be 24 more red boxes) which equals 7800 and 7680 and if you take them away from each other you get 120

Answer: \bold{y=\dfrac{24}{x}} ; indirect variation ; x = 2.4

<u>Step-by-step explanation:</u>

direct variation is when: \dfrac{y}{x}=k   ; where k is the constant rate

indirect variation is when: xy = k  ; where k is the constant rate

In the table provide: x * y = 24 for each coordinate provided, so this is indirect variation, with equation: y = \dfrac{24}{x}

since k = 24, then input y = 10 and k = 24 into the equation above:

10 = \dfrac{24}{x}

10x = 24

x = \dfrac{24}{10}

x = 2.4
