Make an equation for each statement with x being catcher's mitts and y being outfielder's gloves.

x + 10y = 239.50       and        x + 5y = 134.50

Multiply the second equation through by -1 giving -x - 5y = -134.50

Combine the equations vertically

 x + 10y = 239.50
-x   - 5y = -134.50

giving

5y = 105
y = 21

Now substitute for y:
x + 10(21) = 239.50
x + 210 = 239.50
x = 29.50

Thus, Catchers mitts $29.50 and outfielder's gloves are $21

The composite function combines the palm tree and the seed functions

The composite function is t(d) = 60d + 20

<h3>How to determine the composite functions</h3>

The functions are given as:

Number of palm trees: t(s) = 3s + 20

Number of seeds: s(d) = 20d

The composite function that represents the number of palm trees Carlos can expect to grow over a certain number of days is represented as:

t(s(d))

This is calculated as:

t(s(d)) = 3s(d) + 20

Substitute s(d) = 20d

t(s(d)) = 3 * 20d + 20

Evaluate the product

t(s(d)) = 60d + 20

Rewrite as:

t(d) = 60d + 20

Hence, the composite function is t(d) = 60d + 20
