Tim, griff and kay baked chocolate for kay s birthday party. tim baked 3 times as many as kay. griff baked half as many as tim. altogether they baked 88 chocolate. how many did tim make

48


Define the number of cakes they baked in term of x

Let the number of cakes Kay baked be x

Kay = x
Tim = 3x                ← Tim baked 3 times as many as Kay
Griff = 1.5x            ← Griff baked 1/2 as many as Tim


Construct the equation and solve for x

The total number of cakes baked was 88.

x + 3x + 1.5x = 88        ← Combine like terms
5.5 x = 88                     ← Divide by 5.5
÷5.5    ÷5.5
x = 16


Find the number of cakes each baked

Kay = x = 16
TIm = 3x = 16 x 3 = 48
Griff = 1.5x = 1.5(16) = 24


Tim baked 48 cakes.
