How many tiles does she need ?
1 square meter = 10,000 cm²
12 square meters = 120,000 cm²
Each tile = (20 cm x 20 cm) = 400 cm²
Tiles needed = 120,000 / 400 = <u>300 tiles</u>
How many tiles can she buy ?
1,000 / 34.99 = 28 boxes, with 20.28 left over . . . not enough for another box.
28 boxes of 10 tiles per box = <u>280 tiles</u>
Halima doesn't have enough money to buy enough tiles
to cover the wall. She can only buy 280 tiles, but it would
take 300 to cover the wall.
She can cover 280/300 = 93 and 1/3 percent of the wall,
leaving 6 and 2/3 percent with the old ugly plaster showing.
Maybe she could leave the bare part down at the bottom, and
then hide it with a table up against the wall.
18 because 15÷0.75 is 20. 20×.90 is 18.

The general formula to form a parabole equation is written below.
y = a(x - h)² + k
with (x,y) is one of the points lies on the parabola, and (h,k) is the vertex of the parabola.
From the question above, we get this information
(x,y) = (5,24)
(h,k) = (4,9)
The remaining value to find is a. We need to find the value of a to form the equation. Input the numbers to the equation.
y = a(x - h)² + k
24 = a(5 - 4)² + 9
24 = a(1) + 9
24 = a + 9
24 - 9 = a
a = 15
Write the equation, without inputing the value of x and y
y = a(x - h)² + k
y = 15(x - 4)² + 9
<em>This is the equation</em>
