If 3 pounds of apples costs .99 how much does 2 pounds costs?
0.99 / 3 = _?______ per pound
Take it from there.
or, since the ratio of lb/$ is constant,
.99/3 = x/2
To find out how much 2 pounds of apples cost given that 3 pounds cost $0.99, we can use a proportion.
A proportion is an equation that states that two ratios are equal. In this case, we can set up a proportion using the weights and costs of the apples.
The proportion can be written as:
(3 pounds) / ($0.99) = (2 pounds) / (x)
Here, x represents the unknown cost of 2 pounds of apples.
To solve for x, we can cross-multiply and then divide:
(3 pounds) * (x) = (2 pounds) * ($0.99)
3x = 2 * $0.99
Now, we can solve for x:
3x = $1.98
Dividing both sides by 3:
x = $1.98 / 3
So, 2 pounds of apples cost approximately $0.66.
