103 adults and 183 kids have attended.

Step-by-step explanation:

Here is the complete question: At the movies, we had 286 people buy tickets. The adult tickets were $12 and the children´s tickets were $4. The total sold was $1968. How many adults and kids attended?

Given: Total ticket sold is 286

           Cost of each adult ticket is $12

           Cost of each kids tickets is $4

           Cost of total ticket sold is $1968.

Lets assume the number of tickets adult bought be "x".

∴ Ticket bought for kids is

Now, putting the values in an equation to find the number of ticket bought by adult.

We know,

⇒

Using distributive property of multiplication, distributing 4 with 286 and x.

⇒

Subtracting 1144 both side.

⇒

dividing both side by 8

∴ x=

Hence, 103 Adults attended.

Next, subtituting the value of x to find the tickets bought for kids.

Number of tickets bought for kids=

Hence, 183 kids have attended.

Step-by-step explanation:

Mark has been saving up for a $200 pair of sneakers.

He just noticed that the sneakers he wants are on sale for 35% off. The value of 35% off the sneakers that he wants is

35/100 × 200 = 0.35 × 200 = 70

if his mom tells him she will pay for tax, then the amount that he has to pay for the sneakers is

200 - 70 = $130

He has $120. Therefore, he doesn't have enough money to buy the sneakers.

The amount that he needs to save is

130 - 120 = $10
