The cost of each bush is $ 18.49
<h3><u>Solution:</u></h3>Let "f" be the cost of each flower
Let "b" be the cost of each bush
<em><u>Given that Mrs. Kelly buys 15 flowers and 3 bushes for a total cost of $160.32</u></em>
15 flowers x cost of each flower + 3 bushes x cost of each bush = 160.32
15f + 3b = 160.32 ----- eqn 1
<em><u>Each bush costs $11.50 more than each flower</u></em>
Cost of each bush = 11.50 + cost of each flower
b = 11.50 + f ------ eqn 2
<u><em>Let us solve eqn 1 and eqn 2 to find values of "b" and "f"</em></u>
Substitute eqn 2 in eqn 1
15f + 3(11.50 + f) = 160.32
15f + 34.5 + 3f = 160.32
18f = 160.32 - 34.5
18f = 125.82
<h3>f = 6.99</h3>Substitute f = 6.99 in eqn 2
b = 11.50 + 6.99 = 18.49
<h3>b = 18.49</h3>Thus the cost of each bush is $ 18.49
