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.

Sergeeva-Olga [200]

Answer:

The land which are used for exhibits are <u>89 acres</u> (approximately).

Step-by-step explanation:

Given:

Village is spread across 240 acres of land. 37% of land is used for the exhibits.

Now, we have to find acres of land which are used for exhibits.

So, here it is given that land used for exhibits is 37%, and we have to calculate the quantity from the percentage given:

According to question:

37% of 240 acres of land.

$\frac{37}{100}\times 240$

$0.37\times 240$

$88.80$

So, the land used for exhibits are 88.80 acres.

Therefore, the land which are used for exhibits are <u>89 acres </u>(approximately).
