Question

It costs the school band SS dollars per sandwich that they make. The band sells each sandwich for 20\%20% more than it costs to make so they earn a profit. The expression 73(S+0.2S)73(S+0.2S) describes how much money the school band received selling sandwiches at their last fundraiser.

Answer 1

Step-by-step explanation:

The number of sandwiches the the band sold- 73

The cost to make one sandwich- S

The profit the band earns from one sandwich- 0.2S

The amount of money that the band receives for selling one sandwich -S+0.2S

Answer 2

Money Required for making 1 Sandwich that is Cost Price of 1 Sandwich = S Dollar

Selling Price of 1 Sandwich = 20 % more than Cost Price S

                    = S + 20 % of S

                     = $\frac{20S}{100}+S=\frac{120S}{100}$

                     =$ 1.20 S

                      = $(S + 0.20 S)

Selling Price of 73 Sandwiches = $ 73 (S + 0.20 S)

The expression $73(S+0.2 S) →→  Selling Price of 73 Sandwiches
