Answer:

Option (C)

Step-by-step explanation:

Let the relation between amount of money (m) and Time (t) is represented by the equation,

m = ct + b

Where c = Investment per week

b = Ben already had the amount before investment

From the question,

c = $5 per week

b = $100

Therefore, equation will be,

m = 5t + 100

If duration of the investment 't' = 8 weeks

Amount in the account after 8 weeks,

m = 5(8) + 100

m = $140

Option (C) is the correct option.

Enduro solved -4x &gt; 120 by adding 4 to each side of the inequality. What mistake did he make?
Stolb23 [73]

The mistake made by Enduro is that he is supposed to divide both sides by -4 instead of adding 4 to each sides

<h3>What are inequalities?</h3>

Inequalities are expressions that have unequal values, when compared

<h3>How to determine Enduro's mistake?</h3>

The inequality is given as

-4x > 120

When 4 is added to both sides, the inequality becomes

4 - 4x > 120 + 4

The above is not the solution to the inequality.

The solution is as follows:

We have:

-4x > 120

Divide both sides inequality by -4

x < -30

Hence, the mistake made by Enduro is that he is supposed to divide both sides by -4 instead of adding 4 to each sides
