Answer:
$4.75
Step-by-step explanation:
1milliliter = 1mL = 1.0*10^-3L
50mL = 50*10^-3L = 0.05L.
But 0.05L costs $0.19 to refill,
How much will 1.25L cost?
0.05L = 0.19
1.25 = x
X = (1.25*0.19) / 0.05
X = $4.75
It will cost her $4.75 to refill 1.25L of soap
Answer:
$9.5
Step-by-step explanation:
Each dispenser holds 1.25 liters, so we have a total of 1.25*2 = 2.5 liters to be filled.
Each 50 milliliters of soap, that is, 0.05 liters, costs $0.19, so we can solve now using a rule of three:
0.05 liters of soap -> $0.19
2.5 liters of soap -> X
0.05/2.5 = 0.19/X
X = 2.5*0.19/0.05 = $9.5
It will cost $9.5 to fill both dispensers with soap.
