Question

One week gas was $1.75 per gallon. The next week gas was $2.10 per gallon. By what percentage did the price increase or decrease? % (increase or decrease)​

Answer 1

Answer is 20% increase

Rate can be found by subtracting old price from new price and then dividing that by the old price

Old price = $1.75
New price = $2.10

2.10 - 1.75 = .35

.35 / 1.75 = .2 = 20% increase

Check your work

1.75 x 20% = .35

1.75 + .35 = 2.10
