A digital camera memory card is 1/4 full. The card is 2/3 full when 375 more pictures have been taken.
marusya05 [52]
To get the answer first we have to find full numbers.
We can use proportion
2/3 ----------------------- 375
1 -------------------------- x
Crossmultiply now
2/3*x=375           /:2/3 
x=375: \frac{2}{3} 
x=375* \frac{3}{2}=562 - its the answer A)
Now we have to find how much were originally on the card.
To get the answer we can just multiply 562 times 1/4.
562*1/4=140 - its the asnwer B)

Please help me. thank you so much
Sergio [31]

Answer:

7.5

Step-by-step explanation:

So the constant proportionality is easy, it is the depindent veriable (how much it cost) divided by the independent veriable (how much fabric you have).

Put simply you know how much it will cost if you know how many yards you have. so if i have 2 yards i know it cost 15 dolars.

We could make a simple algebraic expretion that describes the proportionality.

C⁒y=7.5

So 7.5 is our constant, so if you know the cost or how many yards we have we always know what the other is.

So if i had 6.7 yards how much would it cost.

It would cost $50.25, what i did was i multiplied 6.7*7.5(our constant) and we got out cost c. Just to dubble check we can plug it in;

50.25⁒6.7 does=7.5 so it works.
