Write an inequality that can be used to fine x, the minimum number of plaques that can be ordered so that the total charge at Company A is less than the total charge at Company B.

Answer 1

Answer:

x=4.33

Step-by-step explanation:

let he total cost be y

Company A charges

y=28+2.5x-----------1

Company B charges

y=15+5.5x--------------2

Equating 1 and 2 we can find x

28+2.5x=15+5.5x

collect like terms

28-15=5.5x-2.5x

13=3x

x= 13/3

x=4.33
