Question 237874
Equation:  {{{y=0.75+0.50x}}}
.
You're very close.  From this equation, we would say x is the amount of times you rode the slide and y would be the amount of money spent. So, if you rode the slide 15 times, the equation would then be:
.
{{{y=0.75+0.50(15)}}}
{{{y=0.75+7.50}}}
y=8.25
.
If you only took somewhere between $8.25 and less than $10.00, would you have enought money to buy a $2 soda? No.  Because you would only have left $1.25 at the most.
