Answer:
7.76(x) / 4 = Total cost
$25.22
Explanation:
Given in the question that,
number of glue sticks that cost $7.76 = 4
To find the cost of 13 glue sticks first we need to find the cost of one glue stick, for that we will need cost of 4 sticks with 4
4 ----> $7.76
1 ----> $7.76/4
$1.94
Multiply the cost of 1 glue with 13
3 -----> $1.94x13
$25.22
Equation
7.76x/4 = Total cost
where x represent number of glue sticks
