Hello!
We are told that the Father’s Day gift was $75, the cost of which was split between three people. This can be represented using the following equation:
(Beth) + (James) + (Buzz) = $75
We know that Beth and James each contributed $25. Now we can rewrite the equation with the given information and then simplify:
$25 + $25 + (Buzz) = $75
$50 + (Buzz) = $75
Now subtract $50 from both sides and simplify:
$50 (-$50) + (Buzz) = $75 (-$50)
Buzz = $25
We have now proved that Buzz contributed $25.
I hope this helps!
Answer:
cost of knife = £5.52
Step-by-step explanation:
Assume:
Cost of Knife = a
Cost of Spoon = b
a = 3b ----------------------(1)
12a + 9b = £82.80 -------(2)
Substitute equation (1) in equation (2)
12 * (3b) + 9b = £82.80
36b + 9b = £82.80
45b = £82.80
b = £1.84
Therefore, cost of knife = a = 3 * £1.84 = £5.52
