Answer:

bags of popcorn = 10%

sodas = 15.78%

overall increase was 12.5%

Step-by-step explanation:

We must calculate the unit price of each product, before and after.

Before:

bags of popcorn = 7.50 / 3 = 2.5

sodas = 3.80 / 2 = 1.9

Then:

bags of popcorn = 8.25 / 3 = 2.75

sodas = 4.40 / 2 = 2.2

Now, we calculate for each:

bags of popcorn = 2.75 / 2.5 = 1.1

which means that the increase was 10%

sodas = 2.2 / 1.9 = 1.1578

Which means that the increase was 15.78%

If we calculate the percentage of total increase it would be:

(2.75 + 2.2) / (2.5 + 1.9) = 1,125

Therefore the overall increase was 12.5%

One number is 5 more than the other. Their sum is 33. Find the numbers.
dimaraw [331]

Answer:

19,14

Step-by-step explanation:

x=5+y

x+ y= 33

we will solve using substitution

(5+y) +y= 33

5+y+y=33

5+2y=33

subtract 5 from both sides

2y=28

y=14

We got y now we will find what x is

for this, we will substitute y's value (14) into the first equation

x=5+(14)

x=19

we got x too
