O=orange
a=apple

equation 1
3o+a=$1.86
a=$1.86-3o

use a=$1.86-3o in equation 2

equation 2
2o+3a=$2.15
2o+3($1.86-3o)=$2.15
2o+$5.58-9o=$2.15
$5.58-7o=$2.15
$5.58=$2.15+7o
$3.43=7o
$0.49=o

then use $0.49=o for equation 1.

equation 1

3($0.49)+a=$1.86
$1.47+a=$1.86
a=$0.39

so an apple is $0.39.

Answer:

946.242 milliliters

Step-by-step explanation:

The client drank 6 ounces of orange juice and 4 ounces of coffee for breakfast. We need to convert ounces to milliliters

1 ounce = 29.574 milliliters

6 ounces of orange juice

= 6 × 29.574 = 177.444 milliliters

4 ounces of coffee = 4 × 29.574 = 118.296 milliliters

For lunch, he consumed 8 ounces of tea and 6 ounces of ginger ale.

8 ounces of tea = 8 × 29.574 =236.529 milliliters

6 ounces of ginger ale = 6 × 29.574 =177.444 milliliters

4 ounces of water at 10:00 a.m. and at 2:00 p.m. this means 8 ounces of water.

8 ounces of water = 8 × 29.574 =236.529 milliliters

Total consumption by the client =

177.444 + 118.296 + 236.529 + 236.529= 946.242 milliliters
