Question

Arthur went to the local taqueria to buy lunch for his family. He can buy
two tacos for the price of one burrito, and the chalupa is $0.75 more
than a burrito. The cost of one burrito is b dollars.

Which expression represents the cost of 2 burritos, 8 tacos and 4 chalupas?

Answer 1

Answer:

$3 + $10b

Explanation:

Cost of 2 tacos = cost of one burrito = $b

Therefore, cost of 8 tacos = 8 × $b/2 = $4b

Cost of 2 burritos = 2×$b = $2b

Cost of chalupa = $0.75 + cost of one burrito = $0.75 + $b

Therefore, cost of 4 chalupas = 4($0.75 + $b) = $3 + $4b

Cost of 2 burritos, 8 tacos and 4 chalupas = $2b + $4b + $3 + $4b = $3 + $10b
