Calvin and Phoebe each have 8 more pastries than Frank but only five less than Grace. If Grace has 30 pastries, calculate the total number of pastries that the four have?
If Grace has 30 pastries, then both Phoebe and Calvin each have 30-5 = <<30-5=25>>25 pastries.
The total number of pastries that Phoebe and Calvin have is 25+25 = <<25+25=50>>50
Together, Phoebe, Calvin, and Grace have 50+30 = <<50+30=80>>80 pastries.
Since Calvin and Phoebe each have 8 more pastries than Frank, then Frank has 25-8 = <<25-8=17>>17 pastries.
Altogether, the four have 17+80 = <<17+80=97>>97 pastries.
