Uncle John sold $(p + 4)$ muffins on Monday. He sold $2p$ more muffins on Tuesday than on Monday. Altogether, he sold 240 muffins on the two days. Find the value of $p$. Ans: ___

1. Express the number of muffins sold on Tuesday in terms of $p$.

Muffins sold on Tuesday = $(p + 4) + 2p = 3p + 4$

2. Form an equation for the total number of muffins sold over the two days.

Total muffins = Monday + Tuesday
$(p + 4) + (3p + 4) = 240$
$4p + 8 = 240$

3. Solve the equation for $p$.

$4p = 240 - 8$
$4p = 232$
$p = \frac{232}{4} = 58$
