Question

A small toy car costs $3. A large toy car costs 5times as much as the small one. Aaron wants to buy one of each. Which equation can he use to find the cost (a) of the two cars.5xa=$3+$3$3+(5x$3)=a(5x$3)/3=a5x($3+$3=a

Answer 1

C. $3 + (5 x $3) = a

cost of small toy car + cost of large toy car

recall,

large toy car cost 5times the small toy car

therefore,

a = $3 + (5 x $3)

$3 which is the cost of the small toy car

(5 x $3) which is the the cost of the large toy car
