Question

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

Answer 1

13 trucks & 52 dolls

Explanation:

Let number of trucks sold be t

and

number of dolls sold be d

Since dolls sold were 4 TIMES of trucks, we can write our 1st equation as:

d = 4t

Also, trucks cost 17 and dolls cost 24 and together they sold 1469, so we can write 2nd equation as:

17t + 24d = 1469

Putting 1st equation in 2nd one, we get an equation in "t" and lets solve for t:

17t + 24(4t) = 1469

17t +96t = 1469

113t = 1469

t = 1469/113 = 13

So, 13 trucks were sold

And, now we know d = 4t, so d = 4(13) = 52

So, 52 dolls were sold
