destiny opens a checking account with $100 and then deposits $27 each week. how many weeks will it take her account to reach $343?

Question

use the equation to solve the problem: 100 + 27w = 343

Answer 1

To solve the equation $100+27w=343$ for $w$, follow these steps:

1. Subtract 100 from both sides of the equation:

$$27w=343-100$$

$$27w=243$$

2. Now, divide both sides by 27 to solve for $w$:

$$w=\frac{243}{27}$$

3. Perform the division:

$$w=9$$

So, it will take Destiny 9 weeks to reach $343 in her checking account.
