If 5 ibs apples cost $2.99, how much would 3 ibs cost?
AnnZ [28]

We know that 5 lbs of apples cost $2.99

To know how much do 3 lbs of apple cost, you can use cross multiplication

If 5 lbs cost $2.99

Then 3 lbs cost $x

The proportion between the price and the number of apples is the same, you have to calculate it as:

\begin{gathered} \frac{2.99}{5}=\frac{x}{3} \\ (\frac{2.99}{5})\cdot3=x \\ x=1.794 \end{gathered}

3 lbs of apples cost $1.79

Through (2,0) slope = -5/3 write the slope intercept of the equation
babunello [35]

For this case we have that the equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

In this case we have the following data:

m = - \frac {5} {3}\\(x, y) :( 2,0)

Then, the equation is of the form:

y = - \frac {5} {3} x + b

We find "b" replacing the point:

0 = - \frac {5} {3} (2) + b\\0 = - \frac {10} {3}\\b = \frac {10} {3}

Thus, the equation is:

y = - \frac {5} {3} x + \frac {10} {3}

Answer:

y = - \frac {5} {3} x + \frac {10} {3}

Lilit [14]

Answer:

73.5

Step-by-step explanation:

Part/whole=percent/100

?/500=2.1%/100

500 divided by 100 is 5, so 2.1% times 5 is 10.5, which is the amount of interest made per year.

So, 10.5 times 7 is 73.5
