Jacob’s family switched the shower head in their bathroom to a water saving model to reduce water usage and save costs. Their old shower head used 2.5 gallons per minute. Their new shower head uses 40% less water per minute. Over a 20 minute shower, how many gallons of water are saved by using the new shower head? $11.75 $26.50 $3.25 $3.50

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so what is the problem what are they asking you to solve
