Answer:
Option 3 - 4/3
Step-by-step explanation:
When solving equations, we use inverse operations. The inverse of 3/4 is the reciprocal 4/3. Option 3 is the solution.
Answer:
The price of the drink is: $4
and the bag of popcorn costed $5.5
Step-by-step explanation:
Let b=the price of each bag of popcorn
Let d=the price of each drink
One bag of popcorn costs $b, so 10 bags of popcorn cost 10b. One drink costs $d, so 6 drinks cost 6d. The total cost 10b+6d equals \$79:
10b+6d=79
Likewise, if 3 bags of popcorn and 5 drinks cost $36.50, then:
3b+5d=36.50
Write System of Equations:
10b+6d=79
3b+5d=36.50
