James and Sarah went out to lunch the price of a lunch for both of them was $20 they tipped their server 20% of that amount. How
Oxana [17]

Answer:

$24

Step-by-step explanation:

James and Sarah's lunches cost $20 each, so the total price of their meal is 20 * 2 = $40.

They tipped their server 20% of $40, so to find 20% of 40 you would multiply:

40 * 0.20 = 8

Add 8 to 40 = $48.

If they shared this lunch price of $48 equally then they each paid half of this price.

48 / 2 = 24

They each paid $24.

(1 + 9.8k)(2.8) simplified
o-na [289]

Answer:

<em>2.8 + 27.44k</em>

Step-by-step explanation:

<u>Algebraic Simplification</u>

The rules of algebra can be applied in some situations to make expressions simplified or expanded, according to the specific needs of each problem.

We are given the expression:

(1 + 9.8k)(2.8)

It's a sum and a product. We cannot add the independent term with the variable term, so we can only multiply the factor and the contents of the parentheses as follows:

(2.8)1 + (2.8)9.8k

Operating:

2.8 + 27.44k
