(# books Lisa has) = 5(#CDs Lisa has) Let *C* be the number of CDs Lisa has. Then 5*C* = 35 Solving this equation gives us *C* = 7, so Lisa has 7 CDs. Sadly, all seven of them are ABBA CDs. You need to expand your horizons and get with the times, Lisa. Although ABBA is pretty cool, we're not going to lie. Disco forever! |
