At first they bought 40 uniforms for $3,000. When divided, the result came out as 75$ per each uniform. If they only received 40$ back then, 70-40=30. So the difference was 30$ per uniform.

Answer:
0.00088383838
Step-by-step explanation:
Our parent function is f(x)=x^2. A vertical stretch by a factor of k means that every point (x,f(x)), has been transformed into (x,kf(x)). Alex is clearly incorrect as our parent function has been transformed to (x,9f(x)), not (x,3f(x)). A horizontal stretch(or compression) by a factor of k means our function has been transformed to (x/k,f(x)). Here, Marta is saying our function should look like (3x,f(x)). This can also be achieved by plugging 3x into the parent function, which would give us f(3x)=(3x)^2, so it seems that Marta is the correct one.
