The State Board of Education has $2,835,515 to buy new calculators. Each calculator costs $99. After buying as many calculators as it can with its budget, how much money will the State Board of Education have left over?

The State Board will be left with $56.

Step-by-step explanation:

⇒ Maximum number of calculators = Total Cost/Cost of 1 calculator

= 2835515/99 = 28641.57 ≈ 28641 (Rounding off)

⇒ 28641 × 99 = $2,835,459

⇒ $2,835,515 - $2,835,459 = $56

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
