$18 * 15% = 2.70
$18 - $2.70 = $15.30
$15.30 * 6% = 0.918
$15.30 + $0.918 = $16.218 = $16.22
To find a percentage, multiply the number by the percentage as a decimal. 20% as a decimal is .2.
50 times .2 is 10
50×.2=x
50×.2 = 10
10=10
20% of 50 is 10!
Let the number of quarter be x and that of nickels be y
total number of coins will be:
x+y=85
thus
x=85-y.........i
total amount of money will be:
0.25x+0.05y=14.25....ii
substituting i in ii we get:
0.25(85-y)+0.05y=14.25
21.25-0.25y+0.05y=14.25
7=0.2y
y=7/0.02
y=35
thus
x=85-35=50
the number of quarters was 50 and that of nickels was 35
0≤x≤2 The lowest you can go without being negative is 0, and the highest you can get without x being equivalent to 14 is 2.
Answer:
2 14/25
Step-by-step explanation:
16/(2+1/2)^2 . simplify 2+1/2 to 5/2
16/(5/2)^2
16/5^2/2^2
16/25/4
16*4/25
64/25
2 14/25
