Question

Olive buys indie music online.Each song costs $2 plus a $5 fee for using the artists site.She has no more than $40 to spend

Answer 1

She can buy 5 songs and still have 7 dollars left

5 + 2 = 7

7 x 5 = 35
Less than 40

7 x 6 = 42
But this is too much

So it would be 5 songs he could buy and still have $7 left. ( 7 x 5 = 35 )

Answer 2

Answer:

$2s+5\leq 40$

Step-by-step explanation:

Givens

• Each song costs $2 plus a $5 fee for using the artist site.
• She only has 40$, not more.

To find an expression that could model this problem, we need to recur to inequalities, because the problem is a about a restriction, that is, she cannot spend more than $40.

Also, the $5 fee is fixed, that is, it represents a constant.

Let's call $s$ each song, the expression would be

$2s+5\leq 40$

Notice, that we use $\leq$ as the retriction sign, which indicates that she cannot spend more than $40. Also, we use 2 as a constant ratio because that's the cost per song.

Therefore, the answer is

$2s+5\leq 40$
