Question

What if Tanisha needs 40 bowls for the picnic? Explain how to write an equation with a letter for an unknown factor to find the num er of packs she should buy. Than find the unknown factor.

Answer 1

We know that each pack has 6 bowls and we need 40 bowls. Let x be the number of packs, then we can write:

$6x=40$

If we move the coefficient of x to the right hand side, we get

$x=\frac{40}{6}$

which gives x= 6.666.

However, the number of packs are integer numbers, so we must round up to the nearest integer. Hence, the answer is 7 packs.
