Answer:
382 children and
312 adults swam
Step-by-step explanation:
Let the number of children be x
And let the number of adult be y
Hence on a hot summer day
x +y = 694 - - - - - - - 1
x= 694-y
Also the daily prices are $ 1.25 for children and $ 2.50 for adults
1.25x + 2.50y= 1257.50-------2
Let us substitute x= 694-y in equation 2
1.25(694-y) + 2.50y =1257.50
867.5-1.25y +2.50y = 1257.50
-1.25y+2.50y= 1257.58-867.5
1.25y= 390
y= 398/1.25
y= 312
Substitute y= 312 in equation 1 to find x
x + 312= 694
x= 694-312
x= 382
Hence 382 children and
312 adults swam
Answer:
37.5
Step-by-step explanation:
split in the middle, 5×5=25/2=12.5
12.5= triangle
5×5=25
25=square
12.5+25=37.5
The formula of the future value of annuity ordinary
Fv=pmt [(1+r/k)^(kn)-1)÷(r/k)]
Fv future value
Pmt payment
R interest rate 0.0425
K compounded monthly 12
N time 10 years
If the payment 150
Fv=150×(((1+0.0425÷12)^(12
×10)−1)÷(0.0425÷12))
=22,381.089
If the payment 200
Fv=200×(((1+0.0425÷12)^(12
×10)−1)÷(0.0425÷12))
=29,841.452
How much more
29,841.45−22,381.09
=7,460.36
Answer:
1040
Step-by-step explanation:
20,000 is how much you have and you would multiply 20,000*5.2% or 20,000*.052 (converting a percent to a decimal.)
