3 pineapples cost the same as 2 mangoes One mango costs 1.35 how much does one pineapple cost

One pineapple costs 1.11

Step-by-step explanation:

3 pineapples = 2 mangoes

1 mango = 1.35

2 mangoes = 1.35 × 2

2 mangoes = 2.7

3 pineapples = 2.7

1 pineapple = 3 ÷ 2.7

1 pineapple = 1.11

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
