Answer: 2 × 12 + 2 × 3 or 2 × (12 + 3)
Step-by-step explanation:
Here, the cost of one song = $ 2
If the downloaded song on Monday was 12,
Then, the total money spend on Monday = 2 × 12
Similarly, If the downloaded song on Tuesday is 3,
Then, the total money spend on Tuesday= 2 × 3
Thus, the total cost of the songs on Monday and Tuesday = 2 × 12 + 2 × 3 Or 2 × ( 12 + 3)
Which is the required numerical expression.
By solving it we get = 2 × 15 = 30
Therefore, he spent $ 30 on Monday and Tuesday in downloading songs.
