d) \( 1.5 \times 3 + 1.5 \times 4 \)

Let's break this down step by step! You can simplify the expression by factoring out the common term \(1.5\). So, it becomes \(1.5 \times (3 + 4)\). That means you first add \(3\) and \(4\) to get \(7\), and then multiply it by \(1.5\). So, the answer is \(1.5 \times 7 = 10.5\)! Now, let's talk about how this concept shows up in real life. This kind of multiplication and addition is super useful in budgeting! For instance, if you're planning a party and you want to calculate the cost of drinks and snacks, you could estimate the total based on the differences in quantity. Knowing how to group and calculate can save you time and help manage your expenses better!
