Daniel can spend no more than $40 at the fair. If admission
into the fair is $10 and the rides cost $1.50 each, which
inequality represents the greatest number of rides Daniel
can go on?

So, the equation would be -

1.50x + 10 = 40

and you have to find the value of x

1.50(?) +10 = 40

The value of x would be 20

1.50 x 20 = 30 +10 = 40

Your answer would be that

Daniel can ride up to 20 rides

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
