First three hours = 85 * 3 = 255
last two hours = (85/2) * 2 = 85
total cost = 340
The Four basic Mathematical Operations are:
•Addition
•Subtraction
•Multiplication
•Division
Find the difference:
1400 - 1250 = 150
Divide the difference by the starting value:
150 / 1250 = 0.12
Multiply by 100:
0.12 x 100 = 12% increase.
Statement Reason
1) 4x + 5 = 17 Given
2) 4x + 5 - 5 = 17 - 5 Subtraction property of equality
3) 4x = 12 Simplifying
4) 4x/4 = 12/4 Division property of equality
5) x = 3 Simplifying
