Answer:
5. Katelyn worked 11 hours at the grocery store.
6. 5pounds of steak
Step-by-step explanation:
5. let x hrs be the no. of hours Katelyn worked at the grocery store.
amnt of money she earnt = 9x + (15-x)×15
= 9x -15x + 225
= -6x + 225
-6x + 225 = 159
6x = 225-159
6x= 66
x= 11
Katelyn worked 11 hours at the grocery store.
6. Let x be the pounds of steak he purchased.
total paid= 13.50x + (8-x)×3.25
= 13.50x -3.25x +26
= 10.25x +26
10.25x+ 26=77.25
10.25x = 77.25-26
10.25x= 51.25
x=5

(1/8)*x one eights of the calories in the banana split
10 calories less than one eights of the calories in the banana split, means
