Hi !
So,here we have to calculate the least common multiple of the numbers 15,25,9,8.
<span>We have to break down every number as a prime number product:</span>
15 = 3·525 = 5² 9 = 3² 8 = 2³
Then,we have to select <span> common and uncommon numbers at the highest power so:
</span><span>
</span><span>lcm : 2³·3²·5² = 8·9·25 = 1800
</span>
Step-by-step explanation:
2 hours -----> $12.50
1 hour -----> $12.50/2 = $6.25
Now, putting it in the form of y = kx,
For 1 hour -----> $6.25 = K×1 (General equation)
Similarly,
For 2 hours -----> $12.50 = K×2
For 5 hours -----> $31.25 = K×5
