how much does one apple cost?
how much does one banana cost?

Apple cost $1.00 while bananas cost $0.35

apples are $0.90 and bananas are $0.40

Step-by-step explanation:

3a+2b=$3.50

a+2b=$1.70

take the second equation and isolate one variable so it becomes a=$1.70-2b then you plug that into the a in the first equation

3($1.70-2b)+2b=$3.50

use the distributive property with the parenthesis

$5.1-6b+2b=$3.50

combine like terms

$5.1-4b=$3.50

subtract $5.1 from both sides

-4b=$-1.6

divide both sides by -4

b=$0.4

plug the $0.4 into the equation for b

3a+2($0.4)=$3.5

multiply the parenthesis

3a+$0.8=$3.5

subtract

3a=$2.7

divide

a=$0.9

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
