Mathematics

To solve this, you would do:

x + 75% * x = 35

7/4 * x = 35

x = 20

A number increased by 75% is the number +75% of the number, or the number plus 0.75 of the number, or 1.75 of the number, or 1.75x (with the number being x). We can do this because a percent is per 100 and we already have 1.0 of the number (1x is equal to x). Since we know that 1.75x is equal to 35, we can set up an equation.

1.75x = 35

Now, we want to get x by itself. We can do this by multiplying both sides by the reciprocal of x.

1.75 * 1/1.75x = 35/1.75

x = 20

That means that 20, increased by 75% is 35.

Jim sold 396 tickets for the school play. Student tickets cost $3 and adult tickets cost $4. Jim's sales totaled $1385. How many
Tamiku [17]
Let student tickets be s and adult tickets be a.  The number of tickets sold of both adult and student then is s + a = 396.  If each student ticket costs $3, then we represent the money equation by tacking the dollar amount onto the ticket.  3s is the cost of one student ticket.  4a is the cost of an adult ticket.  The total money from the sales of both is 4a + 3s = 1385.  We now have a system of equations we can solve for a and s.  If s+a=396, then s = 396-a.  We will sub that into the second equation to get 4a + 3(396-a) = 1385.  Distributing we have 4a+1188-3a=1385.  a = 197.  That means there were 197 adult tickets sold.  If s + a = 396, then s + 197 = 396 and s = 199.  197 adult tickets and 199 student tickets.  There you go!

For the first two, multiply 13 in place of the X. For example, 4(13)+71 = 123.
