Answer:
Total = $49.05
Step-by-step explanation:
cost of grapes per pound = $ 2.50
she bought 3 pounds of grapes
so cost of 3 pounds of grapes = 3 × 2.50
= 7.5
gallon of milk = 8.6 pound
so cost of 8.6 pound of milk = 8.6 × 4.25
= $36.55
$ 1.50 off means =$4 - $ 1.50 = $2.5
cost of 2 boxes of cereal = 2 × 2.5
= $ 5
Total = 7.5 + 36.55 + 5
Total = $49.05
Hello! B and D are eliminated from the start, because you don't multiply by a negative to get the amount you spent. In reality, you would multiply the number of games by the cost of it to get the real price. A doesn't make too much sense, but the negative could represent how much he spent from his allowance. Even with that, it's really not the best answer. The only answer that really works is C. The answer is C.
The x-value at the point, denoted by d, is 18
<h3>Slope of a line </h3>
From the question, we are to determine the x-value at point B on the line
Given the points (x₁, y₁) and (x₂, y₂) on a line.
The slope, m, of a line with two points (x₁, y₁) and (x₂, y₂) on the line is given by the formula
m = (y₂ - y₁)/(x₂ - x₁)
From the given information,
Point A is (2, 1)
Point B is (d, 81)
That is,
x₁ = 2
y₁ = 1
x₂ = d
y₂ = 81
and
slope, m = 5
Thus,
5 = (81 - 1) / (d - 2)
5 = 80/(d -2)
5(d - 2) = 80
5d - 10 = 80
5d = 80 + 10
5d = 90
d = 90/5
d = 18
Hence, the x-value at the point, denoted by d, is 18
