numbers in parenthesis in addition.
Answer:
34.45
Step-by-step explanation:
11÷2 = 5.5
so 5.5x5.30 = 29.15 + 5.30 = 34.45
00 x 0.24 = a x 0.40 + ( 700 -a ) x 0.15 = 0.40 a - 0.15 a + 105.00
<span>168.00 = 0.25a + 105.00 </span>
<span>a = 252 </span>
<span>Solution with 40% ....................252 liters........................ans </span>
<span>Solution with 15 % ...................700 - 252= 448 liters.........................ans</span>
(256 x 1/2) x 1/2 (reduce the numbers
128 x 1/2
solution is 64
