Answer: Jamian bought 20 bagels and 15 donuts
Step-by-step explanation:
Using the equation below:
b + d = 35 ...... i
1.25b + 0.75d = 36.25 ....... ii
Multiply i by 1.25
Multiply ii by 1
1.25b + 1.25d = 43.75 ...... iii
1.25b + 0.75d = 36.25 ....... iv
Subtract iv from iii
0.50d = 7.50
d = 7.50 / 0.50
d = 15
Since b + d = 35
b = 35 - 15
b = 20

Answer: 3</h3>
================================================
Work Shown:
15n+30 = 75
15n+30-30 = 75-30 ... subtract 30 from both sides
15n = 45
15n/15 = 45/15 .... divide both sides by 15
n = 3
