The answer to this problem is 12.5
Answer:
d=45h
Step-by-step explanation:
If we look at the chart, it shows that 1 hour is equal to 45 miles. Then, 2 hours is equal to 90 miles and so on. This means that for every hour the distance is 45 miles. Therefore, the distance=45 miles times the number of hours. This is equivalent to d=45h The number 45 is equal to the number of miles and the "h" is equal to the amount of hours. I hope I didnt confuse you in the process of writing this and have a good day!
Y = total costs to get the berries
x = pounds of berries.

bearing in mind that the $5 is just to get in, so is only paid once, whilst the pounds of berry will vary.
10x -4 (x - 2) = 80
10x + (8 + -4x) = 80
<span>8 + 10x + -4x = 80
</span>8 + 6x = 80
<span>8 + -8 + 6x = 80 + -8
</span><span>6x = 80 + -8
</span>6x = 72
<span>x = 12</span>
