3. At a bargain store, Jamal bought 2 items that each cost the same amount. Isaiah bought 3 items that each cost the same amount, but each was $2.25 less than the items that Jamal bought. Both Jamal and Isaiah paid
the same amount of money. Check your solution by substituting for x in the original equation and then simplifying

Step-by-step explanation:

What Jamal spent = 2x

What Isaiah spent = 3(x - 2.25)

2x = 3(x - 2.25)

= 3x - 6.75 = 2x

= 3x - 2x = 6.75

= x = 6.75

Cost for each item  (Jamal) = 6.75

Total cost for Jamal = 6.75 x 2

=  13.5 $

Cost for one item  ( Isaiah ) = (x - 2.25

= 6.75 - 2.25 = 4.5

Total cost for Isaiah = 4.5 x 3

= 13.5 $

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
