Answer:

Ida makes $ 6960 in 5 weeks.

Step-by-step explanation:

Let the profit of the first week is p.

p = $ 600

Total profits of the five weeks

= p + (p + 0.15p) + (p + p +0.15 p) + (p + p + p + 0.15 p) + (p + p + p + p + 0.15 p)

= 11 p + 0.6 p

= 11 x 600 + 0.6 x 600

= 6600 + 360

= $ 6960

So, Ida makes $ 6960 in 5 weeks.

Solve the equation a + b - c = 180 for a. *​
spin [16.1K]

Answer:

a = 180 - b + c

Step-by-step explanation:

a + b - c = 180

Move b by subtracting b from both sides.

a - c = 180 - b

Move c by adding c to both sides.

a = 180 - b + c

Therefore a equals 180 - b + c.
