Answer: 73 songs
Step-by-step explanation:
The online music club has a one- time registration fee of $13.95 and charges $0.49 to buy each song. Let x represent the number of songs that a member buys. This means that the amount that a member who just joins the music club pays for x songs would be
0.49x + 13.95
If Emma has $50.00 to join the club and buy songs, the maximum number of songs she can buy would be expressed as follows
0.49x + 13.95 = 50
0.49x = 50 - 13.95 = 36.05
x = 36.05/0.49 = 73.57
the maximum number of songs she can buy is 73 since the number of songs cannot be a fraction.
From fraction to decimal: divide the numerator by the denominator
From decimal to percent: move the decimal two places to the right. For example: 0.062=6.2%
From percent to decimal: move the decimal point two steps to the left. For example: 56%=0.56
From decimal to fraction: Rewrite the decimal number number as a fraction (example: <span>2.625=<span>2.6251</span></span>) an then Multiply by 1 to eliminate 3 decimal places, we multiply numerator and denominator by 10 cubed = 1000<span><span><span>2.625/1</span>×<span>1000/1000</span>=<span>2625/1000 and don forget to reduce if possible;)

For this case we must indicate an expression equivalent to:
For properties of powers we have to:
So, the above expression can be rewritten as:
Thus, the resulting expression is:
