X = 16 is the exact value.
We can first find how much the ribbon cost for 1m by setting an equation.
Let $y be the cost for 1m:
0.8y = 5.60
y = 5.60 ÷ 0.8
y = 7
Now that we know 1m of ribbon cost $7, we can proceed to find how much 3.25m ribbon cost by mutiplying the length with the cost:
7 x 3.25
=$22.75
Therefore the answer is $22.75.
Hope it helps!
