Marcy has $150 to buy packages of hot dogs, d, and hamburgers, b, for her booth at the carnival. at her grocery store she found packages of hot dogs cost $6 and packages of hamburgers cost $20. (a) write an equation that can be used to find the possible combination of hot dog and hamburger packages marcy can buy using her budget of exactly $150. (b) solve the equation for d. (c) solve the equation for b.

a)

b)

c)

Step-by-step explanation:

Let d be the number of packages of hot dogs and b be the number of packages of hamburgers.

a)If the cost of a package of hot dogs is $6 and  cost of a package of hamburger is $20, the required equation will be

b) To solve for d, we subtract 20b from both sides, we get

Now, divide 6 from both sides, we get

c) To solve for b, we subtract 6d from both sides, we get

Now, divide 20 from both sides, we get

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
