Bill is purchasing according lessons. There's $20 materials fee and lesson cost $15. Write an equation for the situation and the
n determine how many lessons built if his total was $125.
1 answer:
X = number of lessons, y = total cost
y = 15x + 20 <== ur equation
when total bill was 125...y = 125
125 = 15x + 20
125 - 20 = 15x
105 = 15x
105/15 = x
7 = x <=== if Bill took 7 lessons, it would cost 125 <==
