Lucy plans to spend between $50 and $60, inclusive, on packages of beads and packages of charms. If she buys 5 packages of beads at $4.95 each, how many packages of charms at $6.55 can Lucy buy while staying within her budget?

Respuesta :

She can buy maximum of [tex]5[/tex] packages while staying within her budget.

Minimum spending limit [tex]=[/tex] $[tex]50[/tex].

Maximum spending limit [tex]=[/tex] $[tex]60[/tex].

Cost of one package of beads [tex]=[/tex] $[tex]4.95[/tex].

Number of packages of beads bought [tex]= 5[/tex].

Cost of one package of charms [tex]=[/tex] $[tex]6.55[/tex].

Let the number of packages of beads bought be [tex]x[/tex].

[tex]4.956 \times 5 + x \times 6.55 \geq 50[/tex]

[tex]24.78+6.55x\geq 50[/tex]

[tex]6.55x\geq 25.22[/tex]

[tex]x\geq 3.85[/tex]

[tex]4.956 \times 5 + x \times 6.55 \leq 60[/tex]

[tex]24.78+6.55x\leq 60[/tex]

[tex]6.55x\leq 35.22[/tex]

[tex]x\leq 5.38[/tex]

So, she can buy maximum of [tex]5[/tex] packages while staying within her budget.
