Answer: D
Explanation:
First, we see that each flower basket is the variable x. This is because that is what increases per situation. The constant fee no matter the amount of flower baskets for store A is $15, so for store A our equation is
Total spent=19.25x+15
And similarly, for store B it is
Total spent=17.50x+30
Now, to compare them we want to keep store A LESS THAN (<) store B ,
so we get that 19.25x+15<17.50+30, which is D
