Svetlanka [38]

Answer:

Sandwich sells for  $4.76  .

Step-by-step explanation:

As given

It costs $2.80 to make a sandwich at the local deli shop.

To make a profit, the deli sells it at a price that is 170% of the cost.

170% is written in the decimal form

= \frac{170}{100}

= 1.7

Thus

Sandwich selling cost = 1.7 × Cost of making

Put all the values in the above

Sandwich selling cost = 1.7 × $ 2.80

                                    = $4.76

Therefore the Sandwich sells for  $4.76  .

700a+1200r=1000000       (then plug in the a)
700(1000) +1200r=1000000        (simplify)
700000+1200r=1000000        (subtract 700000 from both sides)
1200r=300000             (divide by 1200 on both sides)
r=250
