Let h = the number of hours Marta works
Her savings in her account can be calculated by:
840 + 15h
This needs to be at least $2650 for her trip, so an inequality to solve:
840 + 15h ≥ 2650, where h is the number of hours worked
Now solve:
15h ≥ 1810
h ≥ 1810/15
h ≥ 
Marta needs to work at least hours in order to have enough money for her trip.
Answer:
13 31/40
Step-by-step explanation:
1) convert both fractions into improper fractions (you can do so by multiplying the whole number by the denominator/bottom part and then adding that to the numerator/top part)
by doing this, you will get 51/8 and 37/5
2) since you need a common denominator in order to add the two fractions, multiply the top and bottom of 51/8 by 5. Then, multiply the top and bottom of 37/5 by 8.
3) Then, add the top numbers together and your answer will be 551/40, which can be simplified into 13 31/40
I hope this helps!
