A company manufactures battery-powered calculators, x, and solar-powered calculators, y. In one day, a maximum of 110 solar-powered and 80 battery-powered calculators can be made. Each solar-powered calculator requires 1 work-hour to produce and each battery-powered calculator requires 2 work-hours. There are a maximum of 200 work-hours available each day. Write 3 inequalities

Step-by-step explanation:

Given that x and y are the numbers of battery-powered calculators and solar-powered calculators respectively.

As a maximum of 110 solar-powered and 80 battery-powered calculators can be made, so

and .

As each solar-powered calculator requires 1 work-hour to produce and each battery-powered calculator requires 2 work-hours

So, total work-hour required to produced x battery-powered calculator and y solar-powered calculator = x+2y

As the maximum available work-hour is 200 hours, so

.

Hence, all 3 inequalities are

step-by-step explanation:

the answer is 128

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
