7.50
25% also equals 1/4 so divide 130.00 by 4 which equals 32.50
subtract 32.50 from 130.00 which equals the cost, 97.50
97.50 minus 90$ is 7.50, therefore that is the answer
Answer:
40 grams
Step-by-step explanation:
y * 25% + x * 10% = 120 * 15%
x = 120 - y
(120-y) * 10% = x * 10%
y * 25% + (120 - y ) * 10% = 120 * 15%
0.25y + 12 - 0.1y = 18
0.15y = 6
y = 6 / 0.15
y = 40
Answer:
2253 in base 6.
Step-by-step explanation:
The place values in base 6 are:
1, 6, 36, 216, 1296 and so on.
We have 537 in base 10 so we first find how many 216's there are in 537:
537 / 216 = 2 remainder 105
Now 105 / 36 = 2 remainder 33
33 / 6 = 5 remainder 3.
So the answer is 2253 in base 6.
