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

Its actually A. and B. Because if a number is at the end of a number like this 7d  its always multiplication.
