Bobby should grow an amount greater than 70-61 = 9 inches to become taller than 70 inches. Therefore, the correct answer is that Bobby must grow an amount of x> 9 inches to be taller than 70 inches.
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

In case you don't know your times-3 numbers well enough to recognize the answer right away, you can check the second data point.
.. a. 2^3 = 8 ≠ 6
.. b. 3^2 = 9 ≠ 6
.. c. 3*2 = 6
.. d. 2 +3 = 5 ≠ 6
Only selection C makes sense.
