Answer:
The regular price of the balls is $8
Step-by-step explanation:
The sporting goods store sales promotion is as follows;
The price of the third ball after buying two balls at regular price = $1.00
The price of the number of balls Coach John pays for the balls he bought = $136
To buy 24 balls, we have;
2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1
Therefore;
The number of balls bought at regular price = The sum of the 2s = 16 balls
The number of balls bought for $1 = 24 - 16 = 8 balls
Let x represent the regular price of the balls, we have;
16 × x + 8 = 136
16·x = 138 - 8 = 128
x = 128/16 = 8
The regular price of the balls = x = $8.

Answer:
Step-by-step explanation:
-8x^2 - 12 + 7x^2 - 9x + 3
-x^2 - 9x - 9
There are five parts to the ratio:
18 ÷ 5 is 3.6.
Therefore you need 10.8l of white paint and 7.2l of blue paint.
10.8l * 2.80 = £30.24
7.2l * 3.50 = £25.20
The total is <span>£55.44</span>
