Pizzazz Publications is having some books printed. The printer charges $800 plus $5 per book. What equation could help me find how many books can be printed for $4,000?
800 + 5x = 4000
800x + 5 = 4000
4000 + 5x= 800
800 + 5 = 4000
4000 = 800 + 5
An electrician charges $90 per hour plus a $50 travelling fee. It costs $1000 in total.
1000 = 50x + 90
1000 = 90x + 50
90 = 1000 + 50x
90x = 1000 + 50
50 = 90x + 1000
Scott works on cars. He charges $35 for each car plus $7 per hour. Write an equation that represents this scenario if Kylie's car bill was $63.
7x + 35 = 63
7x = 63
35x + 7 = 63
35x + 63 = 7
35 + 63x = 7
Penelope is going to the carnival to ride the rides. It costs $20 to get into the carnival and ride tickets are $0.50 each. Write an equation that represents this scenario if she spends $35 in all.
.50x + 20 = 35
.50x = 35
.50 + 20x = 35
.50x + 35 = 20
.50 + 35 = 20x
