agasfer [191]

Answer:

Hand sanitizer=135 bottles

Bar soap=83 bottles

Step-by-step explanation:

Let x represent the hand sanitizer and y the sop.

-Our problem can be expressed as:

x+y=218\ \ \ \ \  ...i\\\\4.25x+2.15y=752.20\ \ \ \ \  ...ii

#Make x the subject in i then substitute in ii to solve;

x=218-y\\\\\therefore 4.25(218-y)+2.15y=752.20\\\\926.5-4.25y+2.15y=752.20\\\\174.3=2.1y\\\\y=83\\\\x=218-83=135

Hence, 135 bottles of hand sanitizer and 83 bottles of bar soap were sold.
