Question

sell at the register. he calculates that he needs to sell 10 candy bars in order to make $36 that day using the following math:
36 - 35 = 1
1 ÷ 0.1 = 10
10 candy bars
write another equation using algebra that can show how micah can calculate how many candy bars he needs to sell.

Explanation:

Step1: Define variable for candy bars

Let $x$ = number of candy bars to sell.

Step2: Set up total earnings equation

Micah's base amount is $35$, plus $0.10$ per candy bar, equal to $36$:
$\boldsymbol{0.1x + 35 = 36}$

Step3: Solve for x

Subtract 35 from both sides:
$0.1x = 36 - 35$
$0.1x = 1$
Divide by 0.1:
$x = \frac{1}{0.1} = 10$

Answer:

$0.1x + 35 = 36$ (solving gives $x=10$)
