To find the unit rate for 5 you would do price/amount
So 5.75/40=.14375 this rounds down to .14
Therefore the correct answer would be B

For 6 the unit rate is the same, meaning you would have to do price/amount, so 2.99/8=.37375 which rounds to .37
So the correct answer is B

motikmotik

Answer:

$-\frac{2}{5}.$

Step-by-step explanation:

1) if to re-write the given equation into slope-interception form, then:

$y=\frac{5}{2}x-7;$

the slope of the given line is 5/2;

2) according to the rule of perpendicular, the required slope should be:

s*(5/2)=-1;

3) if to solve this equation (s*5/2=-1), then s=-2/5 or -0.4.

Extra Credit (5pts) A new pair of shoes is advertised for $75. The sales tax is 8.25%. What is the total cost of the shoes? (Giv

torisob [31]

Answer:

I'm here to help!

First, we need to make a proportion to find the sales tax:

(Let x= Sales tax)

$\frac{100}{8.25} =\frac{75}{x} \\100x=75*8.25\\x=6.1875$

We have the sales tax!

Now we need to estimate, as you cannot have.75 of a cent...

$x=about6.19$

Now to add them:

$75+6.19=81.19$

There you go! The total cost is about 81.19!

Hope this helps!

P.S. Stay Safe!
