Aubrey wants to save money to purchase a new bicycle that costs $275. If she saves $5 per week, how many weeks will it take Aubrey to have enough money to purchase the bicycle?

55 semanas, porque si tomas los $275 y los dividís en  $5 te da 55,lo que serian las semanas

55

Step-by-step explanation:

Set up an equation first like this,

5x=275

you would set it up like this because she needs $275 and she saves her money for a amount of weeks that's why I said x, we want to know the number of weeks.  So you would divide 275 by 5 and you get 55. So she will need to save up for 55 weeks.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
