D<1
Answer:
9 tapes
Step-by-step explanation:
First, subtract the handling charge from his $78.
78 - 3.50 = 74.5
So, Brian has $74.50 to purchase tapes. Each tape costs $7.50, so let's find out how many he can purchase.
74.50 / 7.50 = 9.933 (approximately)
Since Brian can't buy 0.933 of a tape, he will only be able to buy 9 tapes.
To write an equation in point-slope form, we need the slope and a point.
The points given to us by the explanation are (3, 63) and (5, 57) where the x value represents the number of days without rain and the y value represents the depth of the water in inches.
To find the slope, we use the expression:
Change in y/change in x = 63-57/3-5
When simplified, we get: 6/-2 = -3
Therefore, the slope is -3
Note that we can use either of the points in our equation and we will still get the same equation.
Now we just need to substitute in our values:
y = -3(x-3) + 63 which is sometimes written as y - 63 = -3(x-3)
Hope this helps!
