Answer 2

Answer:

it takes 2.56 (or 2 14/25) months

Step-by-step explanation:

Edmond has $45 in his saving account. He wants to purchase a computer that costs $768. He starts to babysit for his cousin and gets paid $90/week. He plans to spend some money and deposit $75/ week in his account. Define a variable and write an equation and solve to find how many months it takes for him to buy the computer. Assume that every month has 4 weeks

Even though Edmond is getting $90 a week, he's only depositing $75

Based on this information your equation would be:

75w = $768 where w = week

To solve that divide 75 by 768

w = 10.24 or 10 6/25

If there are 4 weeks in a month then your new equation would be

w/4 = m where m = months

To solve this, substitute w for 10.24 or 10 6/25

(10.24)/4 = m

m = 2.56 or 2 14/25
