There are 364 first-grade students in park elementary school. If there are 26 more girls than boys, how many girls are there?Use polya's strategy and make an equation.

there are 195 girls

Step-by-step explanation:

the equation is: 364= 2x+26

subtract 26 from both sides and you get 338

338 divided by 2 is 169, therefore there are 169 boys.

169+26 more girls is 195

169+195= 364

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
