bone-shaped treats are five for 3:50 at Shelly store in Sarah wants to buy 12 she set up and solve this proportion to find how m

Valentin [98]

Answer:

8.4 dollars

Step-by-step explanation:

The error is in the resolution of the proportion. In fact, the initial proportion is correct:

$\frac{5}{3.5}=\frac{12}{x}$

where x is the total cost. However, the following step of the resolution is wrong. In fact, the correct resolution is the following:

- Multiplying by x on both sides:

$\frac{5x}{3.5}=12$

- Multiplying by 3.5 no both sides:

$5 x = 12 \cdot 3.5 \\5x = 42$

And now we can find x:

$x=\frac{42}{5}=8.4$

So, the total cost is 8.4 dollars.
