Can i have some help plz

a) 15 + 25x ≤ 70

b) 60 + 15x ≤ 500

Step-by-step explanation:

a) Let x represent the number of calculators that Ms. Burgos can buy. since each calculator cost $25, then the total cost of calculator = $25 * x = $25x

She bought three notebooks costing $5 each. Money spent on notebooks = 3 * $5 = $15

Hence the total money spent = $15 + $25x = 15 + 25x

She has only $70, therefore:

15 + 25x ≤ 70

b) Cayla initially has $60.

Cayla is saving $15 per week. Let us assume she saves for x weeks, hence money saved by Cayla = 15x

Therefore the total money saved = 60 + 15x

Since Cayla needs to save atleast $500, hence:

60 + 15x ≤ 500

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
