Math 128: Three ducks and
two ducklings weigh 32 kg. Four ducks and three ducklings weigh 44 kg. All
ducks weigh the same and all ducklings weigh the same. What is the weight of two
ducks and one duckling?
Let D = the weight of one duck
d = the weight of one duckling
Solve: (3D + 2d = 32)*3 ------> 9D + 6d = 96
(4D + 3d = 44)*2 ------> 8D + 6d = 88
1D + 0d = 8 -----> D = 8 kg
Math 129: A 800 seat
multiplex is divided into 3 theater. There are 270 seats in Theater 1, and there
are 150 more seats in Theater 2 than in Theater 3. How many seats are in Theater
Let x = number of seats in Theater 3
T1 = Theater 1 = 270 seats
T2 = Theater 2 = 150 + x
T1 + T2 + T3 = 800 seats
270 + (150 + x) + x = 800
420 + 2x = 800
x = 190
If there are x = 190 seats in theater 3, then
Theater 2 has
150 + 190 = 340 seats
Math 130: Mary has $50.00.
She goes to the mall and buys lipstick and then she buys shampoo, which is half
the price of the lipstick. She then spends half of what she has left on a purse,
leaving her with $15.00.
How much did the shampoo cost?
How much did the lipstick cost?
Let x = price of lipstick
Let 1/2 x = price of shampoo
Cost of lipstick AND shampoo, combined = x + 1/2 x
Money spent on lipstick AND shampoo combined:
$50.00 - ($15.00)*2 = $20.00
x + 1/2 x = $20.00
1.5x = $20.00
x = $13.33
Lipstick cost: x = $13.33
Shampoo cost: 1/2 x = 1/2 * $13.33 = $6.67
