Answer:
The total number of trucks sold=13
The total number of dolls sold=52
Step-by-step explanation:
Step 1: Determine price per unit of each toy type
Price per doll=$24
Price per truck=$17
Step 2: Derive an expression for the total cost of trucks and dolls sold
Total cost=(Price per doll×number of dolls sold)+(price per truck×number of trucks sold)
where;
Price per doll=$24
Number of dolls sold=d, but 4 times as many dolls than trucks were sold, d=4×t=4 t
Price per truck=$17
Number of trucks sold=t
Total cost=$1469
replacing;
1469=(24×4 t)+(17×t)
96 t+17 t=1469
113 t=1469
t=1469/113
t=13
d=4 t=4×13=52
The total number of trucks sold=t=13
The total number of dolls sold=d=52
