Ian’s monthly allowance is $21. in january he starts saving for a birthday gift in june. each month he saves 2/3 of his allowance. the gift he wants to buy costs $110. will ian have enough money? explain.

He starts saving $ in January to buy a gift in June. (which is 6 months, or 5 months not including June)

Each month he saves 2/3 of his allowance, which is $14.

[his allowance each month is $21, 2/3 of his allowance is $14]

(you multiply 21 by 2/3 = 42/3 = 14)

The gift he wants to buy is $110

x = the number of months

y = total cost

14x = y  

14x = 110    [he saves $14 each month, he wants to have a total of $110 to buy a gift]

Plug in 6 for x in the equation

14(6) = 110

84 = 110   (He is $26 short, so saving either for 5 or 6 months will not get Ian $110)

Ian will not have enough money because he is $26 short for 6 months or $40 short for 5 months. (you can decide whether you want to go by 5 months or 6(including June), sorry for the confusing answer)

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
