L'Anna és una noia molt estalviadora i detallista, en dos anys ha estalviat 140€ per a fer un regal al seu germà. Resulta que li vol regalar unes sabates que tenen una rebaixa del 45,5%, i amb el descompte aplicat el seu preu és de 76€. El problema és que l'Anna no podrà anar a la botiga fins a que acabin les rebaixes, per tant, no podrà comprar les sabates amb el descompte i ha de calcular el seu preu original. Podrà fer el regal al seu germà?

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
