Answer:
The expression is d(45) + 25 = c
Step-by-step explanation:
The expression is d(45) + 25 = c. Let's test it out to see if it is correct. We will test it out by substituting d and c.
Day 1:
- For a day, the expression will be 1(45) + 25 = 70
- => 45 + 25 = 70
- => 70 = 70
Day 2:
- For two days, the expression will be 2(45) + 25 = 115
- => 90 + 25 = 115
- => 115 = 115
Day 3:
- For three days, the expression will be 3(45) + 25 = 160
- => 135 + 25 = 160
- => 160 = 160
Day 4:
- For four days, the expression will be 4(45) + 25 = 205
- => 180 + 25 = 205
- => 205 = 205
Therefore, the expression is d(45) + 25 = c.
Hoped this helped.
