Question

Tom wants to buy some protein bars and magazines for a trip he has decided to buy three times as many protein bars with magazines each protein bar cost $.70 and each magazine cost $2.50 the sales tax rate on both types of these items are 6.5% how many of each item can he buy if he has $20 to spend

Answer 1

Answer:12 Protein bar and 3 magazines

Step-by-step explanation:

Given

Tom purchases Protein bars 3 times as much as magazine

Each bar cost  $\ 0.7$

Each magazine costs $\ 2.50$

Sales tax is 6.5 %

suppose Tom buy x magazines so

Price of magazine is $2.5 x$

Price of bars is $3\times 0.7x=2.1 x$

Total Price$=2.5 x+2.1 x=4.6 x$

After sales tax $=4.6x(1+0.065)=4.899 x$

This must be less than $\ 20$

so $4.899x < 20$

$x< 4.082$

thus $x=4$

so he but 4 magazines and 12 protein bars
