following PEDAS we do operations in parentheses first
10.5-7=3.5
4x3=12
we now have 3.5+12 as our intermediate expression
and 3.5+12 = 15.5

Answer:
Step-by-step explanation:
Number of adults = a
Number of children = c
Total people = 430
a + c = 430 --------------(I)
Total amount =$890
3a + c =890 -----------(II)
Multiply equation (I) by (-1)
(I)*(-1) -a - c = -430
(II) <u>3a + c = 890</u> {Now add and thus c will be eliminated}
2a = 460
a = 460/2
a= 230
Plug in the value of a in equation (I)
230 + c = 430
c = 430 - 230
c = 200
Number of adults = 230
Number of children = 200
