The 2 equations are
x + 2y = 8 → (1)
2x + 4y = 20 → (2)
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:
3
Step-by-step explanation:
First set up your data in order
0,0,0,0,1,1,1,2,2,2,2,3,3
Second subtract the lowest to the highest which is 3-0=3
Hope this helps!
243 = the pages read on Saturday
243 - 53 = 190 = the pages read on Sunday
190 + 243 = 433 = total pages read
Answer = 433
