Answer:
Step-by-step explanation:
The graph is that of the basic absolute value function y = |x|, except that the vertex (0, 0) has been translated 4 units to the right and 7 units down.
Y = 4x - 3
y = mx + b
m = 4
b = -3
y intercept = (0,3)
(x,y) = (0,3)
(x,y) = (1,1) - substitute in ori equation
I assume you mean
2 tonnes of sand
at £75.00 per tonne
20 bags of cement
at £6.70 per bag
350 bricks at 45p each
If so, then
2 tonnes of sand
at £75.00 per tonne = 2 * £75.00 = £150.00
20 bags of cement
at £6.70 per bag = 20 * £6.70 = £134.00
350 bricks at 45p each = 350 * £0.45 = £157.50
Add the three amounts
£150.00 + £134.00 + £157.50 = £441.50
Answer: 441.50
