Erin bought 4 jars of jelly and 6 jars of peanut butter for $19.32. Adam bought 3 jars of jelly and 5 jars of peanut butter for

harkovskaia [24]

Answer:

Step-by-step explanation:

X = cost of PB

Y = cost of J

6X + 4Y = 1932 <--- price is in pennies

5X + 3Y = 1567 <--- price in pennies

Dividing everything in the first equation by 2:

3X + 2Y = 966 <--- price is in pennies

5X + 3Y = 1567 <--- price in pennies

Elimination method... let's multiply the first equation by 3 and the second equation by -2.

9X + 6Y = 2898

-10X + -6Y = -3134

-X = -236

X = 236 --> so the price of the PB is 236 pennies or $2.36

Plugging into the second equation as the numbers are a bit smaller,

5X + 3Y = 1567

5(236) + 3Y = 1567

1180 + 3Y = 1567

3Y = 387

Y = 129. So the price of the jelly is 129 pennies or $1.29.

Now we check: 4 x $1.29 + 6*2.36 = $19.32

3 x $1.29 + 5 x 2.36 = $15.37

The answers are verified and highlighted in bold.

6X + 4Y = 1932 <--- price is in pennies

5X + 3Y = 1567 <--- price in pennies

x + ( x + 1) = 45

2x + 1 = 45

2x = 45 - 1

2x = 44

x = 44 ÷ 2

x = 22
