4.12 Problem solving with inequalities

Construct and solve an inequality for the following situation:

"The sum of $2$2 groups of $x$x and $1$1 is at least $7$7."

Consider the following situation:

"$2$2 less than $4$4 groups of $p$p is no more than $18$18".

Sophia has a budget for school stationery of $\$32$$32, but has already spent $\$15.25$$15.25 on books and folders.

Let $p$p represent the amount that Sophia can spend on other stationery. Write an inequality that shows how much she can spend on other stationery, and solve for $p$p.
