if you go to desmos graphing calculator it'll help you get the solutions for these if you type it in every number and letter and for exponents type ^ its shift then type 6.
Stephen's lunch was $8.33 and Jahmya's lunch was $7.48. Stephen's lunch cost more, by 85¢. If Jahmya leaves a tip, she receives $18.25 back. Hope this helps God Bless!
