Step-by-step explanation:
Answer:she spent 10 hours working in her aunt's store last week.
Step-by-step explanation:
Let x represent the number of hours that Lee spent working at the movie theater.
Let y represent the number of hours that Lee spent working at her aunt's store.
Lee worked a total of 30 hours at the movie theater and her aunt's store. This means that
x + y = 30
Her combined pay from the jobs was $240. She earned $9 per hour working at the movie theater and $6 per hour working in her aunt's store. This means that
9x + 6y = 240 - - - - - - - - - -1
Substituting x = 30 - y into equation 1, it becomes
9(30 - y) + 6y = 240
270 - 9y + 6y = 240
- 9y + 6y = 240 - 270
- 3y = - 30
y = - 30/ - 3 = 10 hours
Answer:
9.93 liter approximately 10 liter
Step-by-step explanation:
3 days = 3/2 quart
3 week = 3/2/3 × 21 quarts
= 1/2×21
=21/2 quarts
now
1 quart = 0.946 liter
21/2 quart = 0.946×21/2 liter
21/2 quart = 9.93 liter
A(n) = 3.50n + 1.00
Martin bought 3^3 apples or 27 apples.
Let n = 27
A(27) = 3.50(27) + 1.00
A(27) = $95.50
