Sara bought a soft drink for four dollars and five candy bars. She spent a total of nineteen

dollars. How much did each candy bar cost?

The cost of each candy bar is $3 ...

Step-by-step explanation:

Let:

x = $4 (soft drink)

z = price of each candy bar

y=5z (Total price of 5 candy bars)

C = $19 (spent money)

The equation is:

C = x+y

$19=$4+5z

Subtract 4 from both sides:

$15=5z

Divide both sides by 5

z=$3

Hence the cost of each candy bar is $3 ...
