Answer:

$3x+2=50$

There are 16 friends at Jack's party.

Step-by-step explanation:

Please consider the complete question.

Jack's mother gave him 50 chocolates to give to his friends at his birthday party. He gave 3 chocolates to each of his friends and still had 2 chocolates left. Write an equation to determine the number of friends (x) at Jack's party. Find the number of friends at Jack's party.

Since there are x friends at party, so chocolate given to x friends would be 3 times x $(3x)$ because Jack gave 3 chocolates to each friend.

As Jack has 2 chocolates left after giving to his friends, so total numbers of chocolates would be $3x+2$ .

Now we will equate total number of chocolates by 50 as:

$3x+2=50$

Therefore, the equation $3x+2=50$ can be used to find number of Jack's friends.

Let us solve for x.

$3x+2-2=50-2$

$3x=48$

$\frac{3x}{3}=\frac{48}{3}$

$x=16$

Therefore, there are 16 friends at Jack's party.

A school administrator bought 6 desk sets. Each set consists of one table and one chair. He paid $48.50 for each chair. If he pa

Marrrta [24]

Answer:

b. $62

Step-by-step explanation:

First, we need to add up the cost of all the chairs.

48.5 x 6 = 291

All the chairs together cost $291

Now we can take out the cost of the chairs from the total.

663 - 291 = 372

$372 is what's left over for the cost of all the tables together. So we are going to divide by the number of tables to find out how much each table costs.

372 / 6 = 62

Each table costs $62
