This math problem has got me stumped: A pack of pretzels costs $4, while a pack of chips is 75% more expensive. Maciek went and bought two packets of chips and two packets of pretzels. How much did he pay for his purchases?
Can you show me the way?
One pack of chips is 75/100 * 4 = $3 more expensive than a pack of pretzels.
That means one pack of chips costs 4 + 3 = $7
So Maciek paid 4 * 2 = $8 for the pretzels
He also paid 7 * 2 = $14 for the chips.
In total Maciek paid 8 + 14 = $22 for his purchases.
