Question

A toymaker was making trucks to sell in his

shop. He made three times as many four-
wheeled trucks as six-wheeled trucks,
He used 54 wheels altogether
How many four-wheel and
siy-wheel trucks did he make?

Answer 1

Answer: 9 Four Wheel and 3 6 Wheel Trucks

Explanation:

Let FW be the four-wheel trucks and SW the six-wheel trucks.

Total wheels is 4*FW + 6*SW and is equal to 54 wheels

We know that FW = 3*SW, so substitute that into the above equation:

4*3*SW + 6*SW = 54

12*SW +6*SW = 54

18*SW = 54

SW = 3

Therefore FW = 3*3 = 9

FW 4 x 9 = 36 wheels

SW 6 x 3 = 18 wheels

Total = 54 wheels
