We need to calculate a TIME. Here, TIME = job / rate
Here,
1 JOB 1 1
------------------------------------- = ------------------ = ---------------
JOB/5 min + JOB/15 min 1/5 + 1/15 3/15+1/15
1
= ------------ minutes = 15/4 minutes = 3 3/4 minutes (answer)
4/15
To answer this question, we first have to set up an equation with variables.
We can use "x" to represent the cost of each bracelet.
Equation: number of bracelets bought × cost of each bracelet = total cost
Number of bracelets bought: 7
Total Cost: 49
Using this information, we can fill in the equation and solve for x.
7x = 49
To isolate x, divide both sides by 7.
x = 7
Since x equals 7, we now know that each bracelet cost $7.
If x=2.5, then 5x would equal 5*2.5, or 12.5
