What does math algebra mean?
The area of mathematics known as algebra is used to portray situations or problems using mathematical expressions. In algebra, we utilize integers with fixed or definite values, such as 2, 7, 0.068, etc. In algebra, we combine integers with variables like x, y, and z.
B. Marina earns $40 per week babysitting and spends $15 per week on coffee, so she has $40 - $15 = $<<40-15=25>>25 left to save each week. Marina needs to save a total of $800 - $200 = $<<800-200=600>>600 to buy the laptop. At the rate of $25 per week, it will take Marina 600 / 25 = <<600/25=24>>24 weeks to save enough money to buy the laptop. Since there are 52 weeks in a year, this means it will take Marina 24 / 52 = <<24/52=0.46>>0.46 years to save enough money to buy the laptop, or about 5.5 months.
C. If Marina decides to use her mom's coffee maker instead of buying lattes, she will save $15 per week. Marina needs to save a total of $600 to buy the laptop, and at the rate of $25 per week, it will take her 600 / 25 = <<600/25=24>>24 weeks to save enough money. This means it will take Marina 24 / 52 = <<24/52=0.46>>0.46 years to save enough money to buy the laptop, or about 5.5 months.
D. It is up to Marina to decide how to use her money. If she values the lattes and is willing to wait longer to save up for the laptop, then she may choose to continue buying them. On the other hand, if she wants to buy the laptop sooner and is willing to give up the lattes, then she may choose to save the money instead. It ultimately depends on Marina's priorities and financial goals.

Marina spends $15 weekly on coffee. It will take her 6 months to save for the laptop with her current spending, or under 4 months if she stops buying lattes. She should weigh the enjoyment of lattes against the goal of buying a laptop sooner.
A. To determine the amount of money Marina spends on coffee each week, we multiply the cost of one latte which is $5 by the number of times she buys a latte in a week, which is three. Therefore, Marina spends $15 on coffee each week.
B. Marina earns $40 a week by babysitting. After spending $15 on lattes, she has $25 left to save. She needs an additional $600 to buy the laptop since she already has $200 saved. Dividing $600 by the weekly savings of $25, we find it will take her 24 weeks, or about 6 months, to save enough to buy the laptop.
C. If Marina uses her mom's coffee maker and saves the entire $40 from babysitting each week, she would save faster. With $600 still needed and saving $40 a week, it would take her 15 weeks, or just under 4 months, to save enough for the laptop.
D. Marina should consider her priorities and the value she places on enjoying lattes versus the desire to buy the laptop sooner. It may be wise to temporarily cut back on lattes or find additional sources of income to achieve her goal faster.
