y = -4
Step-by-step explanation:
12y + 4 = 8y-12
Subtract 8y from each side
12y - 8y +4 = -12
4y +4 = -12
Subtract 4 from each side
4y +4-4 = -12 -4
4y = -16
Divide by 4
4y/4 = -16/4
y = -4
The March sales of Jazz records is an illustration of proportions, and the number of jazz records sold all year is 7x

1).Sugar used in 7 days = 61.25 pounds
2). Total cost of 9 cupcakes = $38.25
Step-by-step explanation:
1). Alani uses 8.75 pounds of sugar each day.
So, sugar used in 7 days = Amount of sugar used in one day × Number of days
= 8.75 × 7
= 61.25 pounds
2). Since, each cupcake costs $4.25
Number of cakes ordered = 9
Total cost of 9 cupcakes = Cost of each cupcake × Number of cupcakes
= 4.25 × 9
= $38.25
