Question

jamar figured that they spend $39 for popcorn .Each movie cost $19 .Write and solve an equation to find how many movies they can purchase.

Answer 1

the complete question in the attached figure

Let

x----------------- > number of DVD movies--------------- > each movie cost $19

y----------------- > total money to spend

we know

cost popcorn------- > $39

then

y=39+19x
y<=100
(39+19x) <= 100------------- > this is the equation required
x>=0
using a graph tool
see the attached figure

the solution is the interval [0,3.21]
the amount of DVD movies must be a whole number
therefore the solution is 3.21------> 3

the answer is 3
