Answer:

  • x - 7.31 ≤ 10
  • x ≤ 17.31

Step-by-step explanation:

let x = the amount of money in the second piggy back

We assume that the second piggy bank has MORE than the piggy bank with $7.31 in it:

x - 7.31 ≤ 10

Solution

Add 7.31 to both sides:  x - 7.31 + 7.31 ≤ 10 + 7.31

                                                       ⇒ x ≤ 17.31
