There were 45 pencils left on the shelf. Janice took 10 pencils and Shanique took n+2 more pencils than Janice. After both girls took pencils, there were 15 left on the shelf. Calculate the total number of pencils that Shanique took.
a. First, we will write the question in equation form. 10+n+2+15 = 45, then; b. Group like terms together, so that we can get "n" by itself 10+15+2+n = 45 27+n = 45 c. In order to get n by itself, we will subtract 27 from both sides, this is to ensure that the equation remains balanced. 27-27+n = 45-27 n= 18 The number of pencils Shanique took = n+2 = 18+2 =20 Therefore, Shanique took 20 pencils.

Annabelle bought chicken and chips for $20.00, soda for $2.00, and a chocolate bar for $0.50. Calculate: a. How much money did her lunch cost? b. If Annabelle gave the cashier $30, how much change did she receive?
a. How much money did her lunch cost? To calculate this, we would have to add the monies together: $20.00+ $2.00+$0.50 = $22.50 So Annabelle's lunch costs $22.50 b. How much change did she receive from $30.00? To find the change received, we would subtract the cost of the lunch from $30.00. Change received =: $30.00 - $22.50 = $7.50. Therefore, Annabelle's change is $7.50.
