If she has 24 chargers total, how many phone chargers does she have? Define a variable ** Let p be the number of phone chargers Anna has and l be the number of laptop chargers. We know that l = 5p and l + p = 24. Write an equation ** Substituting the first equation into the second equation, we get 5p + p = 24 Combine like terms ** Combining like terms, we get 6p = 24 Divide by 6 ** Dividing both sides of the equation by 6, we get p = 4 #### 4 Coral reads 30 pages of a book on night 1, and 2 less than twice that on night 2. Night 3 Coral reads 3 more pages than the sum of the first two nights. How many total pages did Coral read in the 3 nights? How many pages does Coral read on night 1? ** Night 1:30 pages How many pages does Coral read on night 2? ** Night 2:2(30)-2=58 pages How many pages does Coral read on night 3? ** Night 3:3+(30+58)=91 pages How many total pages did Coral read in the 3 nights? ** Total:30+58+91=<<30+58+91=179>>179 pages #### 179 A new condo development has 23 floors. Regular floors have 12 units, whereas penthouse floors have only 2 units. If the top 2 floors are assigned for penthouse units, how many units does this condo have in total? How many floors are there? ** If the condo has 23 floors and the top 2 floors are reserved for penthouse then there are 23-2 = <<23-2=21>>21 floors for regular units How many units are in the regular floors? ** If a regular floor has 12 units each, then 21 regular floors would have 12*21 = <<12*21=252>>252 units How many units are in the penthouse floors? ** If a penthouse floor has 2 units each, then 2 penthouse floors would have 2*2 = <<2*2=4>>4 units How many units does the condo have in total? ** The total units in the property would then be 252 regular + 4 penthouse or 252+4 = <<252+4=256>>256 units #### 256 In her bakery, Teal sells pumpkin pie and custard pie by the slice.
