Answer:
$9.50
Step-by-step explanation:
To figure out how much he spent, you have to multiply the number of games by the cost of each game. 5 games x 0.50 for each game = $2.50 spent. Now to find how much he still has, you have to subtract $2.50 from the $12 that he already has and you get $9.50
First, arrange the data in a table for easy reference:
x y
20 50
30 45
45 55
60 70
80 80
90 90
45 80
120 100
90 95
70 85
Then, use the calculator to find the relationship of the two variables, x (minutes studied) and y (test scores)
The equation is
y = 0.56686x + 38.15
