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

Answer:
rise, run
Step-by-step explanation:
When finding the slope of a line using a slope triangle, the RISE length is divided by the RUN length. (I think. Sometimes the "divided by" makes me confused about which is on top, but I'm pretty sure this is right.)
Step-by-step explanation:
original price (100%) → $19
discounted price ((100-75)%) = (25%) → 25% x $19 = $4.75
