If a toy store sold four times as many dolls then trucks and dials cost $24 each and trucks cost $17 each and they sold $1469 worth how many trucks and dolls were sold each

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

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
