Tina receives a weekly allowance from her parents. She spent half of this week’s allowance at the movies but earned an additional SAR 14 for performing extra chores around the house. If she did not spend any additional money and finished the week with SAR120, what is Tina’s weekly allowance? Write and solve an equation. Tina's goal is to save SAR1000 for her beach trip at the end of the summer. Use the amount of weekly allowance you found in part (a) to write an equation to determine the number of weeks it will take Tina to meet her goal.

86 / 6 = 14.3

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

the correct answers i think are b. and d.

give me brainliest if it is correct!
