Step-by-step explanation:
Let the number of children that swam be A
Let the number of adults that swam be B
1.75A+2B=1113.75 Equation 1
Total number of people that used that pool =602
A+B=602 Equation 2
These are simultaneous Equations
multiply Equation 2 by(2) on both the sides we get
2A+2B=1204 Equation 3
Subtract Equation 1 from Equation 3
2A+2B=1204 Equation 3
1.75A+2b=1113.75 Equation 1
<u> - - -</u>
.25A+0 =90.25
.25A=90.25
A=90.25/.25
A=361
putting value of A in Equation 2 we get
361+B=602
B=602-361
B=241
so number of children is 361
and number of adults is 241
Answer:
6802
Step-by-step explanation:
just multiply 8950 x .76 (which is the 76 percent)
Answer:
x equals to - 5.5 or - 11/2
We know that
if <span>Amy pays 24.50 for 7 tickets
so
cost each ticket is=24.50/7-----> </span>£<span>3.50
find the total number of tickets=</span>£63/£3.50-----> 18 ticket
let
x-----> <span>amount of tickets purchased by Dan
</span>18=7+x -----> x=18-7-----> x=11
the answer is
11
