Question

Saki bought shoes for $40.19 and x pairs of socks for $2.06 each. Which expression shows the total money spent?

40.19x + 2.06
40.19 + 2.06x
40.19x + 2.06x
40.19 + 2.06 + x

Answer 1

let us say, she bought only 3 pairs of socks, what would be an expression for that? if x = 3 that is

Answer 2

the money spent on socks will be multiplied by the number of socks purchased, and you know saki bought exactly 1 pair of shoes, so that's a constant value of 40.19, not dependent on x.

Answer 3

40.19 + 2.06x
