For her birthday Chloe received two gift cards. One of the cards was from Starbuck for $40 and the other was from Soni for $35. Chloe uses the Starbuck card to buy a large coffee each morning for $2.50 and then uses the Sonic card to buy a large cherry-limeade each afternoon for $2.00. Which equation can be used to determine the number of days, x, Chloe can use both cards before the balance is the same on the two cards?

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
