Question

At a student government fundraiser, a notebook costs $5 and a t-shirt costs $11. If the total received for 70 items was $500, how many notebooks were sold"
O 20
O 25
O 45
O 50

Answer 1

Answer:

45

Step-by-step explanation:

t = number of t-shirts

n = number of notebooks

n + t = 70

5n + 11t = 500

n = 70 - t

5(70 - t) + 11t = 500

350 - 5t + 11t = 500

6t = 150

t = 25

n + t = 70

n + 25 = 70

n = 45

Answer: 45
