Jason spent $x on a shirt and 3 times as much on a pair of shoes. He also spent $25 on trousers a. Express the total amount of money spent on the 3 times in ter

A shirt = $x
Price of a pair of shoes is three times as much as a shirt:
A pair of shoes:
3 × $x
= $3x
Trousers = $25

a)
Total amount of money that Jason spend in terms of x:
$x + $3x + $25
= $(x + 3x + 25)
= $(4x + 25)

b)
If x = 18, Jason spend:
$(4x + 25)
= $(4 × 18 + 25)
= $(72 + 25)
= $97
