A silk ribbon costs $5.60 for 0.8m. How much does 3.25m of this silk ribbon cost?
Varvara68 [4.7K]
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!

mr Goodwill [35]
I don’t know what the answer options are so here I go guessing:

M<4 is the opposite but has the same degree
M<6 is the same as M<2
M<8 is the opposite but has the same degree
Any of these are correct. I’m just not sure what the options were/are.
