Answer: her monthly allowance is $630
Step-by-step explanation:
Let x represent her monthly allowance.
Claire spent $450 of her allowance each month and saved the rest. This means that the amount she saved each month is x - 450
If she increased her spending by 18% her savings would decrease by 30%. The expression for an 18% increase in her spending would be
(18/100 × 450) + 450 = 81 + 450
= 531
The expression for a 30% decrease in her savings would be
(x - 45) - [30/100 × (x - 450)]
= (x - 45) - [0.3(x - 450)]
= (x - 45) - [0.3x - 135]
= x - 45 - 0.3x + 135
= x - 0.3x - 45 + 135
= 0.7x + 90
Therefore,
0.7x + 90 = 531
0.7x = 531 - 90
0.7x = 441
x = 441/0.7
x = $630

Answer:
Deductive reasoning
Step-by-step explanation:
Deductive reasoning is based on inference about particular, based on general. Eg : All men are mortal. Ram is a man. So, Ram is mortal [reasoning drew from general 'men' case to particular man 'ram' case]
Similarly, case given : People who eat food high in saturated fat, suffer high cholesterol levels. Dainella eats diet of most foods high in saturated fats. So, her cholesterol level is likely to be high.
Find the difference:
17 - 10 = 7
So the distance between 10 and 17 is 7 on a number line.
A related subtraction fact would be 12-9=3. Hope this helps.
