Answer: $400 was invested
Step-by-step explanation: Based on the scenario in the question, our calculation goes thus:0.11x + 0.06(8000 - x) = 5000.11x + 480 - 0.06x = 5000.11x - 0.06x = 500 - 4800.05x = 20x = 20/0.05x = 400
$400 was invested at 11% Also, 8000 - 400 = 7600 invested at 6%

Answer:
15 boys
Step-by-step explanation:
The ratio is 5 : 12
The 12 part of the ratio relates to the students in the class, that is 36
Divide 36 by 12 to find the value of one part of the ratio
36 ÷ 12 = 3 ← value of 1 part of the ratio, thus
5 × 3 = 15 ← number of boys in class
Answer:
The discount is the same.
Step-by-step explanation:
We need to find the ratios of both discounts.
41/50 = 61.5/75
If the question is True, this means that the ratios should be the same. So we have to cross multiply to find the answer.
75*41 = 50*61.5 = 3075
These two multiplication problems both equal 3075. Since the ratios are equal, the discounts are also equal.
