2 1/2 yds = 2.5 x 36 = 90 inches...what she started with
2 ft 8 in = 2(12) + 8 = 32 inches...what she had left
90 - x = 32
90 - 32 = x
x = 58 inches....so she used 58 inches

The question is asking you to come up with a real-life example of something that can be represented as 15+ c= 17.50. If I were you I would do sales tax. You bought an item with a 15 dollar price tag, but when you go to check out 2.50 are added in tax to equal 17.50. to solve subtract 15 from 17.50: c= 2.50. Your variable (c) represents the sales tax. Hope that helps! :)

Un călător parcurge un drum în trei zile
În prima zi merge o treime din drum și încă 15 km
= 1 / 3x + 15km
A doua zi călătorește două șapte din restul

75 km
Cât de lung este drumul
= 1 / 3x + 15 + 75 + 2/7 (2 / 3x).
