Aconcession stand sells hamburgers (h) for $2 and hotdogs (d) for $1. on friday night they sold a total of 300 hamburgers and hotdogs and made $420. how many of each did they sell?

There are 120 hamburgers

There are 180 hotdogs

Step-by-step explanation:

∵ The cost of h = $2 and the cost of d = $1

∵ h + d = 300 ⇒ (1)

∵ 2h + d = 420 ⇒ (2)

Solve (1) and (2)

Subtract (1) from (2)

∴ (2h + d) - (h + d) = 420 - 300

∴ h = 120

∵ 120 + d = 300

∴ d = 300 - 120 = 180

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!

16

step-by-step explanation:
