Meg opened a savings account with $44.50. She puts in $22.25 in the account each week when she gets paid. She is saving to purchase a blu-ray player that costs $178.00. How many weeks will it take her to save enough money? A. 6 weeks B. 7 weeks C. 8 weeks

Respuesta :

44.5 + 22.25x = 178

Here, you want to isolate the variable and find the number of weeks.

Start by subtracting 44.5 from both 44.5 and 178.

This gives you 133.5

So you're left with 22.25x = 178

Now, you need to divide both numbers by 22.25.

This will leave you with x = 8, meaning it took 8 weeks.
