The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20
.00 for shipping regardless of the size of the order. The band must spend less than $200.00 on bars for the fundraiser. The inequality below relates x, the number of bars that could be ordered, with the shipping costs and their spending requirements. 0.40 x + 20 less-than 200
Which best describes the number of bars the band can order?
They can order from 0 to 449 bars, but no more.
They can order from 0 to 450 bars, but no more.
Their order must contain 451 bars or more.
Their order must contain 452 bars or more.
The common difference of this arithmetic sequence is 5. Adding 5 to an even number gives an odd number, and vice versa. Hence the "parity" of the terms in the sequence must alternate between odd and even.
