Answer:
C. $108
Step-by-step explanation:
Let;
Total amount = x
Brenda = (4/14)x = y
equation 1
4x = 14y
x = 14y/4
equation 2
Tina and Rita = (3/14)x + (7/14)x = y + 162
10x/14 = y + 162
10x = 14(y+162)
10x = 14y+2268
10*(14y/4) = 14y+2268
140y/4 = 14y+2268
140y = 4(14y+2268)
140y = 56y+9072
140y-56y = 9072
84y = 9072
y = 9072/84
y = 108
But;
x = 14y/4
x = (14*108)/4
x = 378
Brenda = 4/14 * 378 = 108
