Answer:
1
Step-by-step explanation:
This is an expression if she only gets pedicure
y = 35
If she wants to get massage, multiply the cost for a minute with the number of minutes.
Find cost per minute first
cost = 50/20
cost = 2.5
So the expression would be
y = 35 + 2.5x
y = 2.5x + 35
2/7.
2/7 + 5/7 =1 Just add the numerator if the denominator is the same
