Answer:

Amount of B used = 276.6 millimeters

Step-by-step explanation:

A = A millimeters

B = A + 400 millimeters

Hence

Taking an overall balance

(0.16 x A) + (0.2)(A+400) = 476

0.16A + 0.2A + 80 = 476

A = 1100 millimeters

B = 1100 + 400 = 1500 millimeters

Hence using direct proportion

2600 --------------------476

1500 ---------------------X

X = 276.61538

Amount of B used = 276.6 millimeters
