Last month nicole spent $30. this month she spent 140% of what she spent last month.
write a proportional equation to represent the situation. how much did nicole spend
this month?

(a) X = $30 + 40% of $30

it could also be written as ; X = 140% of $30

= $ 42

Step-by-step explanation:

Amount spent last month = $30

Let the amount spent this month be x,

Then , x = 140% of $30

x = 140/100 X 30

x = $42

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

the answer is the third / last answer
