We know that
volume of a bar of soap=2*4*0.5----> 4 in³

<span>A bar of soap is sold for $3 individually
</span>so
$3/4-----> 0.75 $/in³

<span>A three-pack of the same soap costs $8
so
$8*(3*4)----> 0.67 $/in</span>³

<span>if you buy the three-pack you save-----> [0.75-0.67]=0.08 $/in</span>³

the answer is
$0.08

The expressions a(8x+7) and 4x+3.5 are equivalent. What is the value of a?
valentina_108 [34]

Answer:

a=1/2

Step-by-step explanation:

From the question, the expression a(8x+7) is equivalent to 4x+3.5

     Which means that multiplying 8x by a gives 4x and multiplying 7 by a gives 3.5

So, we can write the following to find the value of a

a(8x+7)\equiv 4x+3.5

we can write the following

8ax=4x

\implies a=\frac{4x}{8x}= \frac{1}{2}

Hence the value of a is 1/2
