(A) 1280 mL
(B) 1920 mL
(C) 1575 mL
(D) 1680 mL​

Answer 1

(C) 1575 mL

Step-by-step explanation:

Left = Total - Used

4500 mL {1 - (2/5 + 1/4) }

4500 mL {1 - (0.40 + 0.25)}

4500 mL {1 - 0.65}

4500 mL {0.35} = 1575 mL

Answer 2

Answer:

(c)1575

juice used on first day

=2/5of 4500=1800

juice used on second day

=1/4of 4500=1125

total juice used =2925

juice left=4500-2925=1575
