So to find percent increase, you want to minus the difference in cost..

1.09- 0.87= .22...

now divide the difference by the original....

.22 ÷ .87 = .25287.....etc

now multiply that by 100...

.25287 × 100 = 25.287

now it says round to the nearest tenth so...

25.29% increase.

How do you solve 15.00 - 6.24

sdas [7]

Answer:

8.76

Step-by-step explanation:

Simplifying

15.00 + -6.24 = b

Combine like terms: 15.00 + -6.24 = 8.76

8.76 = b

Solving

8.76 = b

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '-1b' to each side of the equation.

8.76 + -1b = b + -1b

Combine like terms: b + -1b = 0

8.76 + -1b = 0

Add '-8.76' to each side of the equation.

8.76 + -8.76 + -1b = 0 + -8.76

Combine like terms: 8.76 + -8.76 = 0.00

0.00 + -1b = 0 + -8.76

-1b = 0 + -8.76

Combine like terms: 0 + -8.76 = -8.76

-1b = -8.76

Divide each side by '-1'.

b = 8.76

Simplifying

b = 8.76
