When Javier and his father went to dinner, the bill was $34. If they tipped the waiter 20%, how much did they spend in total?

Kamila [148]

Answer:

Not sure if this is right, but I got $40.8.

Step-by-step explanation:

I first turned 20% into a decimal. (0.20).

Then I multiplied 0.20 and 34 which is 6.8.

I then added 34 since it’s the original cost to 6.8 since that’s the tip amount.

After that, you should get $40.8.

I am doing with Question Number 2

Let the two numbers be 'x' and 'y'.

According to the question, the product of two numbers is 14.

$x \times y=14$

So, xy=14 (Equation 1)

Now, one of the numbers is 3 ½ times the other.

So, $x = 3\frac{1}{2}\times y$

$x=\frac{7}{2}y$ (Equation 2)

Substituting the value of 'x' from equation 2 in equation 1, we get

$\frac{7}{2}y \times y = 14$

$\frac{7}{2}y^{2} = 14$

$y^{2} = 4$

So, y= 2 and -2

So, $x=\frac{14}{2}$ and $x=\frac{14}{-2}$

x=7 and -7

Numbers are 2,7 and -2,-7.

Sum of numbers 2 and 7 = 9

Sum of numbers -2 and -7 = -9.
